Description
The Renesas OB1203SD and OB1203LC Sensor Modules integrate an optical biosensor with proximity sensor and ambient light sensing features that are desirable for handheld electronic devices. The OB1203 photoplethysmography (PPG) biosensor integrates light sources and drivers, analog digital conversion and I2C communication in a single optical package.
Key Features
- SpO2 measurement less sensitive to skin color
- Industry’s smallest optical biosensor module
- Fully integrated and trimmed module, including two LEDs, 250mA maximum drive current, and photodetectors
- PPG output resolution: 16 to 18 bits
- Data stored in 18-bit wide, 32-sample FIFO memory
- Integrated averaging function for higher signal-to-noise ratio (SNR) and data rate reduction
- Programmable measurement rate: up to 3200 samples per second Light Sensor and Color Sensor* (OB1203SD) Features
- Output resolution: 13 to 20 bits, 3 gain modes
- Very stable spectral response over angle of light incidence
- *High lux accuracy over different light so
