MAX30011

The MAX30011 is a highly integrated, four-channel biopotential analog front end (AFE) for wearable applications, offering both clinical-grade performance and ultra-low power for long battery life.

Each of the four biopotential channels has EMI filtering, internal lead biasing, and extensive calibration voltages for built-in self test. Each biopotential channel also has high input impedance, low noise, high CMRR, programmable gain, an anti-aliasing low-pass filter, and a high-resolution ADC. A set of high-pass and low-pass digital filter options are also available. Further, the MAX30011 provides an active right leg drive (RLD) circuit, pacemaker edge and pulse detection, and a single bioimpedance channel capable of measuring respiration and other BioZ measurements, including the characterization of electrode-tissue interface (ETI) impedances. The device is designed to meet IEC 60601-2-47 Ambulatory ECG System compliance requirements and IEC 60601-2-27 Monitoring ECG System compliance requirements for pace detection.

The BioZ receive channel has EMI filtering and extensive calibration features. It also has high input impedance, low noise, programmable gain, low-pass and high-pass filter options, and a high-resolution ADC. There are several modes for generating stimulus: balanced square-wave source/sink current, sine-wave current, and both sine-wave and square-wave voltage. A balanced square-wave source/sink current generator is provided for simultaneous operation with the electrocardiogram (ECG) channel. A wide range of stimulus frequencies is supported.
