Vishay VCNL36826S proximity sensor

Vishay Inter. introduced two new fully integrated PS designed to increase efficiency and performance in consumer and industrial applications. Featuring an IR emitter and a vertical cavity surface-emitting laser (VCSEL), respectively, the Vishay Semiconductors VCNL36821S and VCNL36826S each combine a photodiode, signal processing IC, and 12-bit ADC in a compact 2.55 mm by 2.05 mm by 1.0 mm surface-mount package. VCNL36826S integrates a PS and a VCSEL into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process.
