General Description

The MAX30002 is a complete bioimpedance (BioZ),

analog front-end (AFE) solution for wearable applications.

It offers high performance for clinical and fitness

applications, with ultra-low-power for long battery life. The

MAX30002 is a single bioimpedance channel capable of

measuring respiration.

The bioimpedance channel has ESD protection, EMI

filtering, internal lead biasing, DC leads-off detection,

ultra-low-power leads-on detection during standby mode,

and a programmable resistive load for built-in self-test.

Soft power-up sequencing ensures no large transients

are injected into the electrodes. The channel also has

high input impedance, low noise, high CMRR, program-

mable gain, various low-pass and high-pass filter options,

and a high resolution analog-to-digital converter. The

bioimpedance channel includes integrated programmable

current drive, works with common electrodes, and has the

flexibility for 2 or 4 electrode measurements. It also has

AC lead off detection.

The MAX30002 is available in a 28-pin TQFN and

30-bump wafer-level package (WLP), operating over the

0°C to +70°C commercial temperature range.

Applications

● Single-Lead Wireless Patches for

In-Patient/Out-Patient Monitoring

● Respiration and Hydration Monitors

● Impedance Based Heart Rate Detection

Benefits and Features

● BioZ AFE with High Resolution Data Converter

• 17 Bits ENOB with 1.1µVP-P Noise for BioZ

● High AC Dynamic Range of 90mVP-P Will Help

Prevent Saturation in the Presence of Motion/Direct

Electrode Hits

● Longer Battery Life Compared to Competing Solutions

• 158µW at 1.1V Supply Voltage

● Leads-On Interrupt Feature Allows to Keep µC in

Deep Sleep Mode Until Valid Lead Condition is

Detected

• Lead-On Detect Current: 0.63µA (typ)

● High Accuracy Allows for More Physiological Data

Extractions

● 8-Word FIFO Allows the MCU to Stay Powered Down

for 256ms with Full Data Acquisition

● High-Speed SPI Interface

● Shutdown Current of 0.58µA (typ)
