Below is a detailed introduction to the product features and application scenarios of four core ADI chips.

I. AD8313 – 0.1 GHz to 2.5 GHz, 70 dB logarithmic detector/controller

The AD8313 is a complete multi-stage demodulating logarithmic amplifier launched by ADI, capable of precisely converting the input radio frequency (RF) signal into an equivalent dB-scaled value at the DC output. Manufactured using ADI’s advanced 25 GHz silicon bipolar IC process, this chip maintains high logarithmic consistency across the signal frequency range of 0.1 GHz to 2.5 GHz.

Key features of the AD8313:

Operating frequency range: 0.1 GHz to 3.5 GHz

High dynamic range: 70 dB (±3.0 dB accuracy)

High precision: ±1.0 dB (65 dB range, 1.9 GHz)

Fast response: 40 ns (typical at full scale)

Wide supply voltage range: 2.7 V to 5.5 V

Low power consumption: 40 mW (3 V supply)

Package: 8-pin MSOP

Operating temperature range: –40 °C to +85 °C

Main Applications of the AD8313:

The AD8313 is specifically designed for RF measurement and power amplifier control applications, and is widely used in RF scenarios such as radar systems, 802.11/Wi-Fi, WiMax and wireless local area networks. Its controller mode features an error output with a gain that remains constant regardless of supply voltage and temperature, making it ideal for system designs requiring high-precision RF power detection.

II. AD8572 – Zero-Drift, Single-Supply RRIO Dual-Channel Operational Amplifier

The AD8572 is a dual-channel zero-drift operational amplifier introduced by ADI, forming part of the AD857x series (the AD8571 is single-channel, the AD8572 is dual-channel, and the AD8574 is quad-channel). This series utilises ADI’s patented spread-spectrum self-stabilising zero technology, which eliminates intermodulation effects caused by the interaction between the chopping function and signal frequency in AC applications.

Key features of the AD8572:

Ultra-low offset voltage: 1 µV

Input offset drift: 0.005 µV/°C

Rail-to-rail input and output swing (RRIO)

Single-supply operation: 2.7 V to 5.5 V

High gain: 145 dB (typical)

Common-mode rejection ratio (CMRR): 140 dB (typical)

Power Supply Rejection Ratio (PSRR): 130 dB (typical)

Gain-Bandwidth Product: 1.5 MHz

Key Applications of the AD8572:

With an offset voltage of just 1 µV and a drift of 0.005 µV/°C—which is virtually zero across the operating temperature range—the AD8572 is particularly well-suited to applications where no sources of error are permitted. It is widely used in precision current sensing, resistive heat detectors, temperature and pressure sensors, medical equipment, electronic scales, strain gauge and thermocouple amplifiers, as well as analogue-to-digital converter (ADC) drivers—all areas where signal accuracy is of the utmost importance. Thanks to its unity-gain stability, this device performs exceptionally well in analogue circuits such as sensor interfaces, data acquisition systems and precision filters.

III. AD5933 – 1 MSPS, 12-bit Impedance Converter Network Analyser

The AD5933 is a high-precision impedance converter system solution introduced by ADI, integrating an on-chip frequency generator with a 12-bit, 1 MSPS analogue-to-digital converter (ADC). The signal generated by the frequency generator excites an external complex impedance; the response signal is sampled by the on-chip ADC and processed via a discrete Fourier transform (DFT) by the on-chip DSP, returning real (R) and imaginary (I) data words at each frequency.

Key features of the AD5933:

Programmable output frequency: up to 100 kHz

Frequency resolution: 27 bits (<0.1 Hz)

Impedance measurement range: 1 kΩ to 10 MΩ (100 Ω to 1 kΩ can be measured with additional circuitry)

System accuracy: 0.5%

Supply voltage: 2.7 V to 5.5 V

On-chip temperature sensor: ±2°C accuracy

Interface: Serial I²C

Package: 16-pin SSOP

Operating temperature range: –40°C to +125°C

Certified for automotive applications

Main Applications of the AD5933:

The AD5933 is widely used in electrochemical analysis, bioimpedance analysis, impedance spectroscopy, complex impedance measurement, corrosion monitoring and protection equipment, biomedical and automotive sensors, proximity sensing, non-destructive testing, material property analysis, and fuel/battery status monitoring.

IV. ADRV9009 – Integrated Dual RF Transmitter, Receiver and Monitor

The ADRV9009 is a highly integrated radio-frequency (RF) agile transceiver from ADI, offering dual-channel transmitters and receivers, an integrated frequency synthesiser and digital signal processing capabilities. This IC features a diverse combination of high performance and low power consumption to meet the requirements of 3G, 4G and 5G macro-cell Time Division Duplex (TDD) base station applications.

Key features of the ADRV9009:

Tuning range: 75 MHz to 6,000 MHz

Maximum receiver bandwidth: 200 MHz

Maximum tunable transmitter synthesis bandwidth: 450 MHz

Maximum monitoring receiver bandwidth: 450 MHz

Dual transmitters + dual receivers + dual-input shared observation receiver

Fully integrated fractional-N RF synthesiser and clock synthesiser

Multi-chip phase synchronisation: supports RF local oscillator and baseband clock synchronisation

JESD204B data path interface: channel rates up to 12.288 Gbps

Package: 12 mm × 12 mm, 196-pin CSP_BGA

Core supply voltage: 1.3 V to 1.8 V

Operating temperature range: –40 °C to +85 °C

Key applications of the ADRV9009:

The ADRV9009 is widely used in 3G/4G/5G TDD macro-cell base stations, TDD active antenna systems, massive MIMO, phased-array radar, electronic warfare, military communications and portable test equipment. The receive path consists of two independent, wide-bandwidth direct-conversion receivers, offering best-in-class dynamic range. The transmitter utilises an innovative direct-conversion modulator, delivering high modulation accuracy and extremely low noise. The high-speed JESD204B interface supports both fixed-point and floating-point data formats; the floating-point format renders the internal AGC invisible to the demodulator.
