일반 설명

The AS7050 Biosignal Sensor Analog Frontend is the next generation Vital Sign Sensor. It enables the user to detect biosignals such as photoplethysmogram (PPG), electrocardiogram (ECG) and galvanic skin resistance (GSR). PPG is the most used HRM method. It measures the pulse rate by sampling light modulated by the blood vessels, which expand and contract as blood pulses through them. ECG is the reference for any measurement of the biopotential generated by the heart. 
Compared to the previous ams-OSRAM biosignal sensor generation, AS7050 is a biosignal converting unit. The AS7050 provides up to 8 LED driver outputs, samples up to 6 photodiode inputs and supports external electrodes. This enables the highest flexibility for several LED and photodiode arrangements in different applications. Furthermore, the AS7050 Biosignal Sensor Analog Frontend provides 2 ADC channels for simultaneous PPG and ECG measurements and an automatic photodiode offset control. The embedded ECG analog front-end satisfies IEC 60601-2-47 requirements.
The AS7050’s low-power design and small form factor are particularly well suited to application in fitness bands, smartwatches, sports watches, smart patches and earbuds. In these cases, board space is limited, and users look for extended, multi-day intervals between battery recharges. Thin package dimension makes the AS7050 suitable for height constrained solution likes earbuds.
