Mouser now offers the AS7050 medical and health sensor from ams OSRAM. The sensor gives design engineers next-generation biosignal conversion for various applications, including smart devices; heart rate, ECG and PPG monitoring; optical sensor platforms; wearables and more.

The device is a biosignal sensor analog front end that provides up to eight LED driver outputs, samples up to six photodiode inputs, and incorporates support for external electrodes, delivering the highest flexibility for multiple LED and photodiode arrangements in various applications. The analog front end provides two ADC channels for simultaneous PPG and ECG measurements and an automatic photodiode offset control. The sensor operates from a supply voltage range of 1.7V to 1.98V and features a 1MHz fast-mode plus, 400kHz fast mode, and 100kHz standard mode through an I²C bus for maximum efficiency.

The company also stocks the ams OSRAM Evaluation Kit for the device, which comprises a main board and breakout board for full flexibility. The breakout board includes a biosensor, accelerometer, temperature sensor, and electrodes that can reconnect to the main board via an FPC cable or external electrodes. The breakout board can also be connected to a wristband through a Molex PicoBlade connector.
