Infrared Receiver Control Receiver Module IRM-36xxC series Features ‧ High protection ability against EMI ‧ Circular lens for improved reception characteristics ‧ Min burst length: 400us ‧ Min gap length: 450us ‧ Low operating voltage (Vcc = 2.5V) ‧ High immunity against ambient light ‧ Long reception range ‧ High sensitivity ‧ Pb free and RoHS compliant 1 2 3 Description The IRM-36xxC devices are miniature type infrared receivers which have been developed and designed by using the latest IC technology, with high immunity against optical interferences and power supply noise. The photo diode and preamplifier are assembled onto a lead frame and molded into an epoxy package which operates as an IR filter. The demodulated output signal can directly be decoded by a microprocessor. Pin Configuration 1. OUT 2. GND 3. VCC Applications • AV equipment such as TV, VCR, DVD, CD, MD, etc. • Toy applications • CATV set top boxes • Multi-media Equipment Application Circuit Block Diagram The RC Filter must be connected as close as possible to Vcc and GND pins.
