MAX30112 Pulse-Oximeter and Heart Rate IC

Maxim's pulse oximetry and heart rate analog front-end is optimized for wearable health

Image of Maxim Integrated MAX30112 Pulse-Oximeter and Heart Rate IC (click to enlarge)Maxim’s MAX30112EWG+ is an optical pulse oximetry and heart rate detection integrated analog front-end (AFE). This AFE offers a high-resolution, optical readout signal-processing channel with built-in ambient light cancellation, as well as high-current LED driver DACs, to form an optical readout signal chain. This product offers very low power and high performance for heart rate detection solutions.

The MAX30112EWG+ operates on a 1.8 V main supply voltage and a separate power supply for LED driver (3.1 V to 5.25 V). This AFE supports an I²C compatible interface, as well as shutdown modes through the software with near-zero standby current, allowing the power rails to remain powered at all times. This device is offered in a WLP package over a -40°C to +85°C operating temperature range.

Applications

  • In-ear wearable devices
  • Fitness wearable devices
  • SpO2 monitoring devices
