MAX30003CTI+

Specialized ICS Overview

The MAX30003CTI+ is a single-channel biopotential analog front-end (AFE) designed for electrocardiogram (ECG) applications. It integrates an input amplifier, programmable gain amplifier, and an 18-bit sigma-delta ADC within a 28-TQFN package. The device operates on a supply voltage ranging from 1.1 V to 2 V and communicates via a serial SPI interface. It provides ECG waveform acquisition and heart rate detection capabilities with low power consumption suitable for wearable devices.
