Unity Opto Technology MIM-93M1AKL Datasheet
INFRARED RECEIVER MODULE
MIM-93M1AKL
Description
o
The MIM-93M1AKL is 37.9 KHZ miniaturized infrared
receivers for remote control and other appplications
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
l Internal filter for PCM frequency
l High immunity against ambient light
l 5-Volt supply voltage; low power consumption
l TTL and CMOS compatibility
