VCNL3036 - Vishay

VCNL3036 High Resolution Digital Biosensor

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 .

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. To accelerate the BIO response time, smart persistence prevents the misjudgment of proximity sensing but also keeps a fast response time. Active force mode, one time trigger by one instruction, is another good approach for more design flexibility to fulfill different kinds of applications with more power saving. VCNL3036 provides an excellent temperature compensa.
