ADPD103: Photometric Front End Data Sheet (Rev. B)4/21/2016PDF1 M
Overview
Features and Benefits
- Multifunction photometric front end
- Fully integrated AFE, ADC, LED drivers, and timing core
- Usable in a broad range of optical measurement applications, including photoplethysmography
- Enables best-in-class ambient light rejection capability without the need for photodiode optical filters
Product Details
The ADPD103 is a highly efficient photometric front end with an integrated 14-bit analog-to-digital converter (ADC) and a 20-bit burst accumulator that works in concert with flexible light emitting diode (LED) drivers. It is designed to stimulate an LED and measure the corresponding optical return signal. The data output and functional configuration occur over a 1.8 V I2C interface. The control circuitry includes flexible LED signaling and synchronous detection.
The analog front end (AFE) features best-in-class rejection of signal offset and corruption due to modulated interference commonly caused by ambient light.
Couple the ADPD103 with a low capacitance photodiode of <100 pF for optimal performance. The ADPD103 can be used with any LED.
Aplications
- Body worn health and fitness monitors, for example, heart rate monitoring
- Clinical measurements, for example, SpO2
- Industrial monitoring
- Background light measurements
