MAX86165

Miniature Optical Heart Rate Module

General Description

Benefits and Features

The MAX86165 is an ultra-low-power, completely integrat-

ed, optical data acquisition system. On the transmitter

side, the MAX86165 has a programmable low-noise LED

driver with an IR emitter. On the receiver side, MAX86165

consists of a high efficiency PIN photodiode and an optical

readout channel. The optical readout has a low-noise sig-

nal conditioning analog front end (AFE), including 20-bit

analog‐to‐digital converter (ADC) and an industry-leading

ambient light cancellation (ALC) circuit. Due to the low

power consumption, compact size, ease and flexibility of

use, the MAX86165 is ideal for a wide variety of optical

sensing applications such as heart rate detection and

proximity sensing in small spaces such as ear buds.

● Complete Single-Channel Optical Data Acquisition

System in a Tiny Module

● Optimized Architecture for Reflective Heart Rate

Monitoring

● Integrated Infrared Proximity Sensing

● Optimized Performance to Detect Continuous

Monitoring for Heart Rate Variability (HRV)

● High-Resolution 20-bit Charge Integrating ADC

● Low-Noise 8-Bit LED Current DAC

● Excellent Signal to Noise Ratio (SNR) up to 94.5dB in

White Card Loop-Back Test

● Excellent Ambient Range and Rejection

• Up to 200μA Ambient DC Current

• 80dB Ambient Rejection at 120Hz

The MAX86165 operates on a single 2.7V to 5.5V V

LED

supply voltage. Each device has a 128-word built-in FIFO.

The MAX86165 is available in a 10-pin OLGA package

with compact package dimensions of 2mm x 2.5mm x

0.82mm and operates over -40ºC to +85ºC temperature

range.

● Ultra Low-Power Operation for Wearable Devices

● Miniature 2mm x 2.5mm x 0.82mm 10-pin OLGA

Package

Applications

● Optimized for In-Ear Applications

● AR/VR Glasses

● Miniature Package for Mobile Applications
