Low-Noise AFE for Pulse Oximeter and Heart

Rate Monitor

MAX86171

General Description

Benefits and Features

The MAX86171 is an ultra-low-power optical data acquisi-

tion system with both transmit and receive channels. On

the transmitter side, the MAX86171 has nine LED driver

output pins, programmable from three high-current, 8-bit

LED drivers. On the receiver side, MAX86171 has two

low-noise charge integrating front-ends that each include

independent 19.5 bit ADCs and best-in-class ambient light

cancellation (ALC) circuits, producing the highest perform-

ing integrated optical data acquisition system on the mar-

ket today.

● Complete Dual-Channel Optical Data Acquisition

System

● Ultra Low-Power Operation for Wearable Devices

• Low-Power Operation, Optical Readout Channel <

11μA at 25 fps

• Exposure Integration Period Ranging from 14.6μs

to 117.1μs

• Low Shutdown Current < 1μA

● Excellent Top-End Dynamic Range > 91dB in White

Card Loop-Back Test (Nyquist Sample-to-Sample

Variance)

● Extended Dynamic Range up to 110dB (Averaging

and Off-Chip Filtering)

● Supports Frame Rates from 1fps to 2.9kfps

● High Resolution 19.5-Bit Charge Integrating ADCs

● Supports Four PD Inputs for Multi-Parameter

Measurements

● Supports Nine LED Driver Output Pins Generated

from Three 8-Bit LED Current Drivers

Due to its low power consumption, compact size, ease

and flexibility of use, the MAX86171 is ideal for a wide va-

riety of optical sensing applications such as pulse-oxime-

try and heart-rate detection.

The MAX86171 operates on a 1.8V main supply voltage

and a 3.1V to 5.5V LED driver supply voltage. The device

supports both I C and SPI compatible interfaces in a fully

autonomous way. The device has a large 256-word built-in

FIFO. The MAX86171 is available in a compact 28-bump

WLP package.

● Low Dark Current Noise of < 50pA RMS (Sample to

Sample Variance in 117.1μs Integration Time)

● Excellent Ambient Range and Rejection Capability

• > 200μA Ambient Photodiode Current

• > 70dB Ambient Rejection at 120Hz (Average Mode

> 2)

Applications

● Wearable Devices for Fitness, Wellness, and Medical

Applications

● Clinical Accuracy

● Suitable for Wrist, Finger, Ear, and Other Locations

● Optimized Performance to Detect:

• Optical Heart Rate

● Miniature 2.78mm x 1.71mm, 7 x 4, 0.35mm Ball Pitch

WLP Package

● -40°C to +85°C Operating Temperature Range

• Heart-Rate Variability

• Oxygen Saturation (SpO )

• Body Hydration

• Muscle and Tissue Oxygen Saturation (SmO and

StO )

• Maximum Oxygen Consumption (VO max)

19-100558; Rev 4; 6/22
