Preamplifier Circuit for IR Remote Control

DESCRIPTION The VSOP383.. is designed for use in an IR receiver application together with a photo pin diode. It is a sophisticated receiver concept that is very sensitive to data signals and compatible with the most common data formats for IR remote control. On the other hand it is immune to
