Description
The IRM-37xxM series devices are miniature type
infrared receivers which have been developed and
designed by using the latest IC technology, specially
optimized to suppress interferences from TFT
backlight.
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.

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).
4. The measurement system is shown in Fig.-3
