MAX30002CWV+

Analog Front End (AFE) Overview

The MAX30002CWV+ is a single-channel bioimpedance analog front-end (AFE) manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 18-bit sigma-delta ADC with a resolution of 20 bits and supports sampling rates from 125 S/s to 512 S/s. The device operates on a supply voltage range of 1.1 V to 2 V for both analog and digital sections, consuming approximately 158 µW of power. It features a differential input type, SPI interface, and 3-state output. Packaged in a 30-WLP (2.74x2.93 mm) format, it functions within a temperature range of 0°C to +70°C.
