ADIMAX30001CWV+
Overview
The MAX30001CWV+ is a complete, single-channel integrated biopotential and bioimpedance (BioZ) Analog Front-End (AFE) solution for wearable applications. It provides high-performance ECG and respiration measurement capabilities with ultra-low power consumption, operating as low as 1.1V. The device features a 20-bit ADC, high input impedance, and built-in heart rate detection to offload processing from the host microcontroller.
Why Choose This Part
The AFE features a massive input impedance of over 1G ohm and high AC dynamic range, ensuring signal integrity despite electrode-skin interface challenges. Integrated FIFO buffers for both ECG and BioZ data, along with a hardware-based heart rate detection algorithm, significantly reduce the duty cycle and power consumption of the system MCU.
Applications
Key Specifications
Getting Started
Designers can evaluate the chip using the MAX30001EVKIT evaluation system, which includes a GUI for register configuration and real-time data visualization. Communication is handled via a standard 4-wire SPI interface, and the device requires a minimal external component count to implement a full ECG solution in its compact 30-WLP package.
