I. Delta-Sigma (ΔΣ) ADC: 128/256-channel current-input precision AFE

This series represents one of the most technically advanced products within the MPS range of data converters. It is specifically designed for direct current-domain digitisation of photodiode arrays, incorporating a current-to-voltage (I/V) conversion circuit and a ΔΣ analogue-to-digital converter within a single chip, thereby eliminating the need for an external transimpedance amplifier. It is widely used in signal front-ends for security scanners, industrial non-destructive testing and CT equipment.

MDC91128 — 128-channel, 20-bit current-input ΔΣ ADC

The architecture utilises 128 parallel signal channels, each featuring a selectable-gain integrator paired with a 20-bit ΔΣ ADC. It offers single-ended current input, with an integration time that can be flexibly adjusted to the 166 μs range. Key specifications include 20-bit resolution, a sampling rate of approximately 6 ksps, an input range of 4 to 25 pC, and noise as low as 20 ppm (FS, RMS); the device features an on-chip 32×128-word data buffer and supports dual serial interfaces. Power is supplied via a 5 V analogue power supply paired with a 1.8 V digital power supply. It is housed in a BGA-440 package measuring 10 × 10 mm and operates within a temperature range of −40 °C to +85 °C.

Application tags: Suitable for 2D industrial X-ray scanning, 3D computed tomography (CT), baggage security scanners and high-channel-count photodiode array digitisation.

MDC91127 — 128-channel, 16-bit cost

Retaining the same BGA-440 package, 128-channel configuration, 32×128-word on-chip buffer and dual serial interfaces as the MDC91128, this version reduces the resolution to 16-bit and adjusts the noise specifications accordingly. It is designed for X-ray imaging and non-destructive testing equipment requiring moderate image dynamic range and where BOM costs need to be controlled.

MDC91256 — 256-channel, 20-bit current-input ΔΣ ADC

Doubling the number of channels compared to the MDC91128, this device offers 256 channels, 20-bit resolution and a sampling rate of 6 ksps. It features a built-in 32×256-word data buffer, whilst the interface has been upgraded to four serial interfaces to support higher data throughput. The integration time is adjustable over a wide range from 166 μs to 0.1 s. It supports daisy-chain cascading, enabling the construction of large detector arrays with over 128 channels; the system clock operates at up to 40 MHz, and it utilises the same 5 V analogue + 1.8 V digital power supply. It is packaged in a BGA-783 package measuring 20 × 20 mm, with an operating temperature range of −40 °C to +85 °C .

Application tags: Designed for large-area flat-panel X-ray detectors, high-resolution CT and multi-row detector arrays; a single device can achieve signal acquisition for ultra-large-pixel channels.

II. SAR ADC: 1 Msps, 8/10/12-bit, ultra-compact TSOT-23-6 package

MPS SAR ADCs offer a lightweight solution characterised by single-channel operation, high speed, low power consumption and no external reference requirement. The three devices are pin- and package-compatible, differing only in resolution and accuracy, allowing for seamless up- or down-scaling during the product design phase.

MDC97476

12-bit, 1 Msps successive approximation architecture, single-ended signal input, SPI-compatible three-wire interface; Typical SINAD of approximately 72 dB (at 120 kHz input), THD < −84 dB, and DNL < ±0.4 LSB, offering excellent linearity amongst products in the compact TSOT-23-6 package. The device derives its reference directly from the VDD supply, eliminating the need for an external reference source and significantly reducing the number of external components; It is housed in a 6-pin TSOT-23 package, operates on a single 3.0 V to 3.6 V power supply, and has an operating temperature range of −40 °C to +85 °C. Typical power consumption is approximately 4.9 mW.

Application tags: Suitable for rapid sensor scanning, industrial process control (IPC), instrumentation, power and system monitoring, as well as space-constrained portable and wearable devices.

MDC97477

A 10-bit, 1 Msps SAR ADC with packaging, power supply, interface and power consumption specifications identical to those of the MDC97476. With a typical SNR of 61.7 dBFS and a typical INL of 0.15 LSB, it meets medium-precision signal acquisition requirements and is suitable for cost-sensitive industrial monitoring applications.

MDC97478

An 8-bit, 1 Msps SAR ADC, also housed in a TSOT-23-6 package, powered by a single 3.0–3.6 V supply, with a typical power consumption of 4.9 mW, a typical SNR of 50 dBFS and a typical INL of 0.04 LSB. It is intended for applications with modest accuracy requirements, such as simple voltage signal acquisition and basic system status monitoring.

III. Integrated ADC+DAC: MP5494 – Highly Integrated AFE for Photonics Control

MP5494 — A high-precision, highly integrated analogue front-end for photonics control

This is the only device in the MPS data converter product line to integrate a precision ADC and DAC on a single chip. It is designed for optical modules and silicon photonics control applications, and is used for laser bias adjustment, modulator drive and closed-loop control of optical power monitoring. The device is housed in a WLCSP-56 package measuring 3.6 × 3.5 mm, meeting the stringent PCB layout constraints of optical modules whilst occupying a minimal footprint.

Application tags: Designed for precision analogue control in high-speed optical modules, silicon photonics transceivers and photonic links, this is a core component through which MPS is extending its data conversion technology into optical communications infrastructure.
