ams OSRAM AS7050 medical and health sensor

The AS7050 is a medical and health sensor from ams OSRAM. It provides design engineers with next-generation biosignal conversion for a variety of applications, including smart devices, heart rate, electrocardiogram (ECG) and photoplethysmography (PPG) monitoring, optical sensor platforms, wearables and more.

The product is a biosignal sensor analog front end that offers up to eight LED driver outputs, samples up to six photodiode inputs and includes support for external electrodes, enabling high flexibility for multiple LED and photodiode arrangements in different applications. The analog front end provides two analog-to-digital converter (ADC) channels for simultaneous PPG and ECG measurements and an automatic photodiode offset control.

The sensor operates from a supply voltage range of 1.7 to 1.98 V and features a 1 MHz fast-mode plus, 400 MHz fast mode and 100 MHz standard mode through an I²C bus for maximum efficiency.
