ADUCM356BCCZ

Overview

The ADUCM356BCCZ is a precision analog microcontroller featuring an Arm Cortex-M3 processor and a dedicated electrochemical sensor interface. It integrates a 16-bit, 400 kSPS ADC with programmable gain amplifier (PGA) and built-in antialias filter. The device includes dual low-power potentiostat amplifiers, three transimpedance amplifiers (TIA), and multiple digital-to-analog converters (DACs). Memory consists of 256 kB flash and 64 kB SRAM. Operating from a 2.8 V to 3.6 V supply, it supports impedance measurements from <1 Ω to 10 MΩ and operates within a temperature range of −40°C to +85°C in a 72-lead LGA package.
