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.
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.

Test method
The specified electro-optical characteristics are valid under the following conditions.
1. Measurement environment
A place without extreme light reflections.
2. External light
The environment contains an ordinary, white fluorescent lamp without high frequency modulation. The
color temperature is 2856K and the illumination at the IR receiver is less than 10 Lux (Ev 10Lux)
≦
.
3. Standard transmitter
The test transmitter is calibrated by using the circuit shown in figure 2. The radiation intensity of the
transmitter is adjusted until Vo=400mVp-p. Both, the test transmitter and the photo diode, have a peak
wavelength of 940nm. The photo diode for calibration is PD438B (λp=940nm, Vr=5V).
