INFRARED RECEIVER MODULE
MIM-3xx7K8
Description
The MIM-3xx7K8 is miniaturized infrared receivers for
remote control and other applications requiring improved
ambient light rejection.
The separate PIN diode and preamplifier IC are assembled
on a single leadframe.
The epoxy package contains a special IR filter.
This module has excellent performance even in disturbed
ambient light applications and provides protection against
uncontrolled output pulses.
Features
l Photo detector and preamplifier in one package
