The AS7058 is an integrated multi-vital sign monitoring device, which provides a complete photoplethysmogram (PPG), electrocardiogram (ECG), body impedance (BioZ), and electrodermal activity (EDA). PPG measures the pulse rate or blood oxygen 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. With EDA, it is possible to measure the skin’s water content, and with BioZ, the body composition with an electrical system.

The AS7057 Biosignal Sensor Analog Frontend (AFE) is the next generation Vital Sign Sensor. It enables the user to detect biosignals such as photoplethysmogram (PPG) and pulse transit time (PTT), as well as proximity. 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. Apart from HRM/HRV, optical Blood Pressure and SpO2 are also enabled by the two independent working photodiode inputs of the AS7057. The AS7057 is a size and performance optimized analog frontend to support space-limited applications such as in-ear vital sign monitoring.The AS7057 provides three LED driver outputs, samples up to three photodiode inputs, and supports proximity detection integrated into one of the PPG signal channels. This enables high flexibility for several LED and photodiode arrangements in different applications. Furthermore, the AS7057 Biosignal Sensor Analog Frontend provides two ADC channels for simultaneous PPG measurements and an automatic photodiode offset control.The AS7057’s low-power design and small form factor are particularly well-suited for application in earbuds, fitness bands, smartwatches, sports watches, and smart patches. In these cases, board space is limited, and users look for extended, multi-day intervals between battery recharges. A thin package dimension makes the AS7057 suitable for height-constrained solutions like earbuds.

The SFH 7018A & SFH 7018B feature a highly reflective QFN package for significantly increased light output. Their sophisticated 2-cavity design reduces interferences between green chip on the one hand and red and IR chip on the other hand. Furthermore, the 2 cavities enables the light sources to be optimally placed relative to their respective photodiodes. Overall this leads to higher accuracy of measurement of vital signs (e.g. heart rate, SpO2). The SFH 7018A is optimized for low Vf at high current allowing operation without voltage booster in many cases.
