会社ブログについて Mingjiada Offers High Prices for ADI Ultrasonic AFE Chips: AD9671 / AD9675 / AD9271 Series Analog Front-Ends

Against the backdrop of the continued expansion of the global medical ultrasound imaging ASIC market, the supply chain value of analog front-end (AFE) chips—as core components of the receive chain in ultrasound devices—is being reevaluated. According to QYResearch data, the global medical ultrasound imaging ASIC market is projected to reach approximately $579 million in 2025 and is expected to climb to $1.034 billion by 2032, representing a compound annual growth rate (CAGR) of 8.7%. AFE chips perform critical functions—including low-noise amplification, gain adjustment, anti-aliasing filtering, and analog-to-digital conversion—of the faint echo signals received by ultrasound transducers, directly determining the dynamic range and signal-to-noise ratio of ultrasound images. For this reason, ADI’s (Analog Devices) eight-channel ultrasound AFE series—including the AD9671, AD9675, and AD9271—have long been characterized by “high value, high scarcity, and high market demand.”

Mingjiada Electronics is now offering high-price cash buybacks for ADI ultrasonic AFE chips nationwide and overseas, with a focus on the full range of AD9671, AD9675, and AD9271 models. We provide a professional, compliant, and fast one-stop solution for monetizing factory inventory, distributor overstock, project surplus, and clearance stock.

Technical Positioning and Recycling Value Analysis of the Three Ultrasonic AFE Chips

Although the AD9671, AD9675, and AD9271 all belong to ADI’s 8-channel ultrasonic AFE family, they each have distinct focuses in terms of resolution, sampling rate, interface architecture, and target applications; consequently, their recycling pricing logic also differs.

AD9671: Integrated digital demodulation; the primary AFE for mid-to-high-end ultrasonic and non-destructive testing applications. The AD9671 integrates 8-channel LNAs, VGAs, AAFs, and 14-bit ADCs, along with a built-in digital demodulator, decimator, and JESD204B serial interface. Power consumption per channel is 150 mW (40 MSPS) in TGC mode, further reduced to 62.5 mW in CW mode, and less than 30 mW in shutdown mode. Its LNA delivers input-referred noise as low as 0.78 nV/√Hz, with a maximum channel gain of 52 dB. Housed in a 10 mm × 10 mm, 144-pin CSP_BGA package, it is designed for portable and cart-mounted systems in medical ultrasound and non-destructive testing (NDT) applications that are sensitive to channel density and power consumption. When recycling the AD9671, the AD9671KBCZ is the core part number; the condition of the package—whether complete, in original factory tape, or on a tray—directly affects its valuation.

AD9675: RF decimation + JESD204B—a high-end choice that balances sampling rate and signal-to-noise ratio. The AD9675 also features an 8-channel, 14-bit architecture, but its key advantages lie in its on-chip 2x RF decimator and a maximum sampling rate of 125 MSPS, with a signal-to-noise ratio (SNR) of 75 dB. Its power consumption is consistent with that of the AD9671: 150 mW per channel in TGC mode (40 MSPS) and 62.5 mW per channel in CW mode. ADI positions this device as an 8-channel ultrasound AFE “recommended for new designs,” for which there is a clear and sustained demand in mid-to-high-end portable and handheld medical ultrasound systems. For customers holding AD9675KBCZ inventory, Mingjiada can provide competitive buyback quotes based on real-time market conditions.

AD9271: A classic 12-bit architecture with a large surplus inventory and significant demand for the buyback of obsolete parts. The AD9271 is one of the earlier 8-channel solutions in ADI’s ultrasound AFE family to enter mass production. It integrates an LNA, VGA, AAF, and a 12-bit ADC, with sampling rates ranging from 10 MSPS to 50 MSPS and per-channel power consumption between 115 mW (at 10 MSPS) and 175 mW (at 50 MSPS). It is housed in a 100-pin TQFP (14 mm × 14 mm) package, with primary part numbers including AD9271BSVZ-40, AD9271BSVZ-50, and AD9271BSVZRL-40. It is currently listed as “in production” on ADI’s official website. Although the AD9271 falls short of the AD967x series in terms of resolution and interface specifications, a large number of existing ultrasound devices still use this platform. The repair and spare parts market, along with small and medium-sized equipment manufacturers, maintain stable demand for it. Factory end-of-line stock, project surplus materials, and distributor clearance inventory are the primary targets for AD9271 recovery.

Why Is the Recycling Window for Ultrasound AFE Chips Opening?

The recycling value of ultrasound AFE chips is not static but is driven by structural factors on both the supply and demand sides. On the demand side, the global ultrasound AFE chip market reached 5.973 billion yuan in 2025 and is projected to maintain a compound annual growth rate of 8.2% over the next six years. Medical ultrasound equipment manufacturers’ reliance on ADI’s high-performance AFEs is unlikely to be fully replaced in the short term, particularly the JESD204B high-speed serial interface solutions represented by the AD9671 and AD9675, which remain the mainstream choice in the fields of high-end portable ultrasound and industrial nondestructive testing. From the supply side, the wafer fabrication and packaging cycles for AFE chips are relatively long. Fluctuations in original manufacturers’ lead times often push downstream customers toward the spot market and secondary distribution channels, creating significant premium pricing opportunities for inventory held through official channels.

Meanwhile, following project changes, product iterations, or production line adjustments, many factories and R&D institutions find themselves with surplus stocks of AD9671, AD9675, and AD9271 materials often find themselves in a situation where “there is a price but no market” or “information asymmetry” exists—holders are unaware of current buyback rates, while buyers struggle to access reliable sources. Mingjiada Electronics’ role in this process is to connect dispersed ultrasonic AFE inventory with genuine market demand and eliminate price information gaps through professional evaluation.

Mingjiada Electronics’ Core Advantages in Recycling ADI Ultrasonic AFEs

With nearly three decades of deep expertise in recycling, Mingjiada Electronics does not engage in “broad-based collection” but rather “selective collection” of ultrasonic AFEs. Founded in 1996, Mingjiada Electronics has accumulated over 20 years of industry experience in electronic component recycling and inventory circulation. With service locations in Japan, Hong Kong, the United States, Canada, Germany, Hungary, and other regions, the company possesses both global delivery capabilities and localized response capacity. For the ADI ultrasonic AFE series, Mingjiada’s evaluation team is well-versed in the part number systems, packaging variations, and lifecycle statuses of the AD9671, AD9675, and AD9271. This expertise prevents the common issue of underestimating the actual value of ultrasonic-specific AFEs that arises from “valuing them as generic ICs.”

We offer high-value cash payments, with our offers generally exceeding standard industry buyback prices. Leveraging a global semiconductor component distribution network, Mingjiada Electronics typically offers prices for ADI high-speed ADCs and AFEs that are 5% to 15% higher than standard industry buyback rates, with no middlemen driving down prices at every stage. We support both cash and corporate account settlements and accept both large and small batches. In the Pearl River Delta region, we can arrange on-site inspections; we also provide unified evaluation and purchase of idle inventory—whether packed by the entire warehouse or mixed with multiple models—eliminating the need for customers to sort components individually.

We accept only components sourced through legitimate channels, ensuring compliant and transparent transactions. Mingjiada solemnly pledges to recycle electronic components exclusively from legitimate sources such as distributors, traders, and end-user manufacturers; we do not accept components of unknown origin or those sourced through unauthorized channels. For high-value ultrasonic AFEs such as the AD9671, AD9675, and AD9271, verifying compliance with legitimate channels is not only a prerequisite for safeguarding the security of our customers’ transactions but also the foundation for maintaining competitive buyback prices and the credibility of long-term partnerships. Customers need only provide an inventory list or part number information, and Mingjiada will provide a preliminary evaluation and price range—the process is simple and efficient.
