MIM-93M1AKL INFRARED RECEIVER MODULE Description 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 5-Volt supply voltage; low power consumption l l TTL and CMOS compatibility unit : mm BLOCK DIAGRAM VS TRAP ABLC Unity Opto Technology Co., Ltd.
