Maxim MAX30001 Biopotential Analog Front-End Solution
Maxim’s MAX30001 is a complete biopotential and bioimpedance analog front end for wearables, offering high performance and low power consumption. The MAX30001 has high-resolution ADCs for clinical-grade measurements, providing ECG waveforms, heart rate, pacemaker edge detection, and respiration. The inputs have integrated ESD protection, EMI filtering, and lead biasing. It also has ultralow power leads-on detection, large FIFO buffers that provide 256 ms of full data acquisition, and built-in heart rate detection, all of which allow the MCU to consume less power, conserving battery life. The biopotential channel offers a high DC offset range for use with a variety of electrodes and provides fast recovery from overdrive events.
