ADUCM356BCCZ

ADUCM356BCCZ is a precision analogue microcontroller with a chemical sensor interface. It is an on-chip system that controls and measures electrochemical sensors and biosensors. It is an ultralow power, mixed-signal microcontroller based on the Arm® Cortex™-M3 processor. This device features current, voltage, and impedance measurement capability. It features a 16bit, 400kSPS, multichannel successive approximation register (SAR) analogue-to-digital converter (ADC) with input buffers, built-in antialias filter (AAF), and programmable gain amplifier (PGA). The current inputs include three trans-impedance amplifiers (TIA) with programmable gain and load resistors for measuring different sensor types. It is used in applications such as gas detection, food quality, environmental sensing (air, water, and soil), blood glucose meters, life sciences and biosensing analysis, bioimpedance measurements, general amperometry, voltammetry, and impedance spectroscopy functions.
