Overview

The LV9005M is an optical sensor switch IC that is fabricated in a medium breakdown voltage BiCMOS process. The LV9005M circuit structure includes a high-gain optical sensor amplifier, a comparator, an oscillator circuit, output drivers, LED drivers, and a synchronous detection and delay circuit. The use of this IC and a minimal number of external components allows the implementations of multifunction high-sensitivity applications that previously would have only been possible with a custom optical-switch IC.

Functions and Features

? Can be used with a wide range of supply voltages; from 5 to 30 V.
