MAX30131/MAX30132/MAX30134

1-, 2-, 4-Channel, Ultra-Low Power Electrochemical Sensor AFEs

General Description

Beneﬁts and Features

● Multichannel Operation

The MAX30131/MAX30132/MAX30134 are 1-, 2-, and 4-chan-

nel (respectively) ultra-low power programmable analog front

ends (AFE) for use with electrochemical sensors. The devices

provide the biasing and complete measurement path, includ-

ing the analog to digital converters (ADCs). The flexibility of

the MAX30131/MAX30132/MAX30134 enables them to work

with both two and three terminal electrochemical sensors,

providing both DC current measurement and electrochemical

impedance spectroscopy (EIS) measurement capability. The

devices include an internal temperature sensor and program-

mable voltage reference to support external temperature

monitoring, and an external reference source to integrate

voltage monitoring of bias and supply voltages for safety and

compliance.

• Up to Four Independent DC Channels

• 1 Switchable EIS Channel

● High Accuracy and Precision

• Up to Four 12-Bit Voltage DACs

• Up to Four 16-Bit Current ADCs

- Programmable 0.8pA to 30pA Resolution

• One 16-Bit EIS ADC

- Programmable 0.014Hz to 27kHz Sine Wave Drive

• 12-Bit Voltage System ADC

• 16-Bit Temperature Sensor

• Programmable, 30ppm/°C Voltage Reference

● Autonomous Modes with 256 Word Configurable FIFO

and Programmable Alarm

The MAX30131/MAX30132/MAX30134 support single-, dual-,

and quad- two-terminal or three-terminal electrochemical sen-

sors, respectively. Ultra-low power allows for the continuous

biasing of the sensor to maintain accuracy and fast response

when a measurement is required. The MAX30131/MAX30132/

MAX30134 operate over a 1.73V to 5.0V voltage range. Total

current consumption can be less than 5μA depending on the

configuration, measurement frequency, and number of sen-

sors. Communication is through a 4-pin SPI serial interface

plus a configurable interrupt pin and four configurable general

purpose input/outputs (GPIOs) for direct control of internal

functions.

● Long Battery Life for 2- and 3-Terminal Sensors

• 3.5μA Continuous Bias Supply Current for Single 2-

or 3-Terminal Sensor

• Add 0.25μA for Each Additional Sensor

● Small Size

• 25-Bump WLP 2.93mm x 2.93mm

● Safety and Compliance

• Monitor Sensor Bias Voltages for Compliance

• Monitor Supply/Battery Voltage and Temperature

● Simple and Robust Digital Interface

• 8MHz 4-Wire SPI Interface

• Programmable Interrupt

The MAX30131/MAX30132/MAX30134 are available in a

25-bump WLP package and operate over a 0°C to +70°C

temperature range.

• Four Programmable GPIOs

● IEC61000-4-2 ESD: ±15kV Air, ±8kV Contact On Sensor

Pins

Applications

● Electrochemical Sensors

● Continuous Glucose Monitors

● Sweat Sensors

● Wearable Devices
