MIM-R1AA38-1 INFRARED RECEIVER MODULE Description Package Dimensions The MIM-R1AA38-1 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. MIM-R1AA38-1 Features unit : mm 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 10±0.3 12.5±0.4 CENTER OF SENSOR 9.2±0.5 30.6±0.52 0.8max. 0.65 1.4±0.3 1 2 3 0.4±0.05 1 Vout 0.5±0.05 4±0.3 2 2.54 3 GND 5.8±0.3 5.08 Vcc Notes : 1.
