Overview

The MAX86141ENP+T is an ultra-low-power, integrated optical data acquisition system designed for heart rate monitoring and oximetry. It features two readout channels that can operate simultaneously, supporting both transmissive and reflective sensing configurations with a high-resolution 19-bit ADC. The device is optimized for wearable applications where minimal board space and long battery life are critical requirements.

Why Choose This Part

The sensor provides industry-leading ambient light cancellation and a 'picket fence' algorithm to reject fast transients, ensuring signal integrity in challenging environments. Its extremely low power profile, consuming only 11uA of quiescent current, significantly extends the operating life of small battery-powered devices.

Applications

Wearable Pulse Oximetry
High-accuracy SpO2 monitoring in smartwatches and fitness trackers using the dual-channel optical front end.
Heart Rate Variability (HRV)
Utilizing the 19-bit resolution and low-noise floor to detect subtle changes in heart rate timing.
Clinical Grade Health Monitors
Integration into medical patches or handheld diagnostic devices requiring SPI communication and low power consumption.
Sports Performance Tracking
Robust heart rate monitoring during physical activity facilitated by the picket fence detect-and-replace algorithm for ambient transient rejection.
