- Highly integrated new ultra -low power AS7058 supports complex PPG applications, ECG and skin electrical activity measurement
- AS7058 AFE introduces physical impedance measurement function, so that wearable devices can analyze body components
- Design for wearable devices such as smart watches, smart rings, smart bracelets and other wearable devices
The new AS7058 also provides a new method of distinguishing wearable products, introducing the ability to perform physical impedance measurement and physical composition analysis.
AS7058's ultra -low noise characteristics can generate 120DB extremely high optical signal -to -noise ratio.Compared with competitive products, this has substantial improvement in PPG measurement properties such as heart rate, respiratory rate, blood oxygen saturation (SPO2) and blood pressure.AS7058's excellent optical noise performance is the results of two low noise, 20 -bit mold converter integration, integrated low noise LED drive, and introducing new automatic ambient light offsetting technology.
The signal -to -noise ratio of AS7058 also enables wearable device manufacturers to reduce power consumption by driving LEDs at lower currents while maintaining high signal integrity.
"If the healthy monitoring and output of smart watches can be transformed into medical feasible data from the approximate indicator of lifestyle to feasible data, the value of the product on consumers will be greatly increased if the health monitoring and output of smart watches can be greatly increased.PPG measurement of optical noise base to help achieve, smart watches, smart rings, and other wearable devices rely on PPG measurement to obtain high -quality life signs data. "
High integration of photoelectric measurement function
AS7058 integrated a comprehensive set of photoelectricity function of life body.it includes:
- Two current absorbers, used to drive eight LED transmitters (four LED/current absorbers)
- Eight photoelectric diode input
- Two 20 -bit ADCs used for PPG measurement
- 20-bit digital modulus (DAC), for electrical measurement of ECG (ECG), body impedance measurement (BIO-Z) or skin electrical activity (EDA).The measurement value of the medical grade electrocardiogram of the device complies with the specifications of the IEC 60601-2-47 standard
Two PPG ADCs perform optical diode data collection at the same time.The measurement of PPG and ECG signals can also be synchronized to achieve blood pressure measurement.
AS7058 is integrated into a compact WLCSP chip. The size of the chip is 2.8 mm x 2.5 mm x 0.5 mm.
AS7058 adds a broad optical and electrical product portfolio of AMS OSRAM, providing a unified source of components and system professional knowledge for the monitoring of consumer equipment life signs.The OSRAM products for AMS for life signs include LED, photoelectric diode and temperature sensor, as well as AS705X series AFE.Hardware products are supported by measurement functions such as heart rate, respiratory rate, and blood oxygen saturation.
AMS Osram also provides a complete hardware demonstration system for surveillance of life signs in the form of smart watches.Customers can benefit from the experience obtained in the development process to reduce design risks and speed up the time of listing.
