The TSOP2238 from Vishay is a miniaturized IR receiver module for remote control systems. A PIN diode and a preamplifier are assembled on lead frame, the epoxy package contains an IR filter. The demodulated output signal can be directly connected to a microprocessor for decoding. This device is mostly used for remote controlling.
o Photo detector and preamplifier in one package
o Internal filter for PCM frequency
o Improved shielding against EMI
o Transmission range of 45m
o Improved immunity against ambient light
o Carrier frequency of 38 kHz
o Directivity of 45°
