VCNL3036
Vishay Semiconductors
High Resolution Digital Biosensor for Wearable Applications With I2C Interface
VDD 1 SCL 2 GND 3 LED3 4
8 SDA 7 INT 6 LED1 5 LED2
DESCRIPTION
VCNL3036 integrates a biosensor (BIO), a mux, and a driver for up to 3 external IREDs / LEDs into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. BIO programmable interrupt features of individual high and low thresholds offers the best utilization of resource and power saving on the microcontroller.
The biosensor features an intelligent cancellation scheme, so that cross talk phenomenon is eliminated effectively.
