MAX30110

Optimized Pulse-Oximeter and

Heart Rate AFE forWearable Health

● Receive Section

General Description

• 19-bit Optical ADC Path to Support the Lowest

Perfusions Situations

• Low 25pA-RMS Input Referred Noise to Minimize

LED Power Under Most Conditions

The MAX30110 is a complete optical pulse oximetry and

heart rate detection integrated analog front-end. The

MAX30110 has a high-resolution, optical readout signal-

processing channel with built-in ambient light cancellation,

aswellashigh-currentLEDdriverDACs,toformacomplete

optical readout signal chain. With external LED(s) and

photo diode(s), the MAX30110 offers the lowest power,

highest performance heart rate detection solution for wrist

applications.

• High Ambient Light Input Range of 200μA and

to Support Extraction of HRM Signal in the Most

Adverse Lighting Conditions

• Built-in Front And Back-End Ambient Light Cancellation,

Improving Rejection and Eliminating System

Complexity of Dealing with Ambient Light

• Short Exposure Pulse Widths of 52μs, 104μs,

206μs, 417μs for Efﬁcient Uses of LED Light

• Multiple Sample Rate Options from 20sps to

3.2ksps

The MAX30110 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 SPI 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.

● Ultra-Low-Power Operation for Mobile and Body-

Wearable Device

• Dynamic Power-Down Modes to 100sps for

Low-Power Consumption

• Full AFE Power Consumption of Less Than 25μA

(Typ) at 25sps

Applications

● Wrist-Worn Wearable Devices

● In-Ear Wearable Devices

• Large 32 Sample FIFO to Support Batch Processing

in the Microcontroller

• Variety of System Monitors Mappable to Interrupts

to Off-Load System Monitoring Functions From the

Microcontroller

● SpO Monitoring Devices

● Fitness Wearable Devices

Beneﬁts and Features

● Reflective or Transmissive Heart Rate, Heart Rate

• Low Shutdown Current = 1.4μA (typ)

Variability, or SpO Monitoring

● SPI Interface

● Transmit Section

● Supports a Single 1.8V Supply with Separate 3.1V to

• Two 8-bit LED Current DACs

5.25V LED Supply

• Four Current Ranges 50mA, 100mA, 150mA, 200mA

• Low Noise Current Sources for High Peak Transmit

to Receive Dynamic Range

● Miniature 2.8mm x 2.0mm, 6x4, 0.4mm Ball Pitch

WLP Package

• Low 160mV Dropout to Support Direct Drive From

Rechargeable Li Battery

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

• High Output Impedance and High Supply Rejection

to Support Unregulated Supply or Direct Drive

From Boost Switcher Supply
