Product Overview

OB1203SD-C4V is a heart rate, blood oxygen concentration, pulse oximetry, proximity, light and color sensor. It integrates an optical biosensor with proximity sensor and ambient light sensing features that is 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. Data from the OB1203 biosensor can be used to determine heart rate (HR), oxygen saturation (SpO2), respiration rate (RR), and heart rate variability (HRV), a measure of stress. The OB1203SD optical filters provide enhanced immunity to ambient light for proximity sensing (PS) and PPG measurements. The OB1203’s longer wavelength far red (690nm) LED is less sensitive to the differences between light and dark skin tones than traditional sensors operating at shorter wavelengths where melanin absorption is stronger.
  • Highly reliable and industry-proven OSIP package with integrated non-allergenic cover glass
  • Wide supply voltage range from 1.7V to 3.6V (VDD = 2.8V, TAMB = 25°C)
  • LS/CS (clear and color sensor) active mode current is 110µA typ (TAMB = 25ºC)
  • PS: 90µA + LED current (typical ~300µA average)
  • Low standby current is 2µA typical
  • I2C interface supporting standard mode (100KHz) or fast mode (400KHz) communication
  • Programmable level-based interrupt function with upper/lower threshold for extending battery life
  • Very stable spectral response over angle of light incidence
  • Measurement resolution is 15bit typical (VDD = 2.8V, TAMB = 25°C)
  • 14-OSIP package, ambient temperature range from -40°C to +85°C
