MAX86180

High SNR Dual-Channel AFE for Multi-Wavelength Optical Spectroscopy

General Description

Beneﬁts and Features

● Complete Dual-Channel Optical Data Acquisition System

● Works Efficiently with Dual as well as Single Stand-Alone

Supply

● Supports Connection with up to 32 Individual LEDs

● Samples up to 20 Unique Exposure Measurements in a

Single Time Frame

● Ultra Low-Power Operation for Body Wearable Devices

• Low-Power Operation, Optical Readout Channel <

20μA at 25fps

The MAX86180 is an ultra-low-power optical data acquisi-

tion system with both transmit and receive channels. On the

transmitter side, the MAX86180 has two, high-current 8-bit

programmable LED drivers. The MAX86180 can drive up to

32 LEDs. On the receiver side, MAX86180 has two low-noise

charge integrating front-ends such that each include indepen-

dent 20-bit analog-to-digital converters (ADCs) and best-in-

class ambient light cancellation (ALC) circuits, producing the

highest performing integrated optical data acquisition system

in the market today.

• Exposure Integration Period Ranging from 14.6μs to

118.2μs

• Low Shutdown Current < 1.1μA

Due to its low power consumption, compact size, ease and

flexibility of use, the MAX86180 is ideal for a wide variety of

optical sensing applications such as pulse oximetry and heart

rate detection.

● Excellent Top-End SNR = 98.7dB in White Card Loop-

Back Test (Nyquist Sample-to-Sample Variance)

● Extended Dynamic Range up to 120dB (Averaging and

Off-Chip Filtering)

● Improved Ambient Light Rejection to Over 90dB at 120Hz

● Supports Frame Rates from 1fps to 1927.53fps

● High Resolution 20-bit Charge Integrating ADCs

● Low Dark Current Noise of < 52pA RMS (Sample-to-

Sample Variance in 118.2μs Integration Time)

● Excellent Ambient Range and Rejection Capability

• > 200μA Ambient Photodetector Current

The MAX86180 operates on a 3.3V analog supply voltage,

a 3.5V to 5.5V LED driver supply voltage, and a 1.8V digital

supply voltage. With two integrated LDOs, the MAX86180 can

operate on a single 3.5V V

supply. The device supports

LED

both I C and SPI compatible interfaces in a fully autonomous

way. The device has a large 512-word built-in FIFO. The

MAX86180 is available in 7 x 5 35-bump wafer-level package

(WLP) with package dimensions of 2mm x 2.63mm and oper-

ates over -40ºC to +85ºC temperature range.

• >90dB Ambient Rejection at 120Hz (Average Mode > 2)

Applications

● Wearable Devices for Fitness, Wellness, and Medical

Applications

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

● Optimized Performance to Detect

• Heart Rate

• Heart Rate Variability

• Oxygen Saturation (SpO )

• Body Hydration

• Optical Spectroscopy
