Description
The device is miniature SMD type infrared receiver that has been developed and designed by utilizing the latest IC
technology.
The PIN diode and preamplifier are assembled onto a lead frame and molded into an epoxy package which operated 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).
