INFRARED RECEIVER MODULE |
MIM-0KM1AKL |
|
|
Description
The MIM-0KM1AKL is 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
Photo detector and preamplifier in one package Internal filter for PCM frequency
High immunity against ambient light
Improved shielding against electric field disturbance 2.4-Volt supply voltage; low power consumption TTL and CMOS compatibility
