MIM-R1AA38 INFRARED RECEIVER MODULE Description Package Dimensions The MIM-R1AA38 series are 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 Improved shielding against electric field disturbance l 5-Volt supply voltage; low power consumption l TTL and CMOS compatibility MIM-R1AA38 Unit: mm 30.6±0.5 12.5±0.4 10±0.3 1 GND 2 Vcc 3 Vout CENTER OF SENSOR 9.2±0.5 0.8max. 0.65 1 2 3 0.5±0.050 1.4±0.3 0.4±0.050 4±0.3 2.54 7.62 5.8±0.3 Notes : 1.
