Maxim MAX30112EWG+T

血氧计/心率I²C-40°C ~ 85°C

Overview

The MAX30112EWG+T is a complete optical pulse oximetry and heart rate detection integrated analog front-end. The MAX30112EWG+T has a high-resolution, optical readout signal-processing channel with built-in ambient light cancellation, as well as high-current LED driver DACs, to form a complete optical readout signal chain. With external LED(s) and photo diode(s), the MAX30112EWG+T offers the lowest power, highest performance heart rate detection solution for wrist applications. The MAX30112EWG+T operates on a 1.8V main supply voltage, with a separate 3.1V to 5.25V LED driver power supply. The device supports a standard I2C compatible interface, as well as shutdown modes through the software with near-zero standby current, allowing the power rails to remain powered at all times.
