The MAX86161 in-ear heart rate monitor (Fig. 1) delivers best-in-class signal-to-noise ratio (SNR) for continuous heart-rate and oxygen-saturation (SpO2) measurements. It incorporates three programmable, high-current LED drivers, yet only requires a single voltage source from 3.0 to 5.5 V. The receiver uses a high-efficiency PIN photodiode with an optical readout channel. This channel has a low-noise signal conditioning analog front-end (AFE) that consists of a 19-bit ADC, and an ambient-light-cancellation (ALC) circuit to support a picket-fence detect-and-replace algorithm.
