MAX30134EWA+T

Translators, Level Shifters Overview

The MAX30134EWA+T is a four-channel ultra-low-power analog front end (AFE) designed for electrochemical sensors. It integrates four 12-bit voltage DACs, four 16-bit current ADCs, and one 16-bit EIS ADC. The device supports DC and electrochemical impedance spectroscopy measurements with programmable resolution from 0.8pA to 30pA. It features a 256-word FIFO, programmable alarms, and an SPI interface operating up to 8MHz. Powered by 1.7V to 5.5V supplies, it consumes approximately 3.5µA per sensor in continuous bias mode.
