Features and Applications

The TSOP2238 is a part of TSOP2#.. series IR Receiver Modules for Remote Control Systems. These products are miniaturized receivers for infrared remote control systems. The demodulated output signal can be directly decoded by a microprocessor.

A PIN diode and a preamplifier are assembled on a lead frame, the epoxy package acts as an IR filter. It has an Operating temperature ranges b/w -25 °C to 85 °C.


  • Low supply current
  • Photo detector and preamplifier in one package
  • Internal filter for PCM frequency
  • Improved shielding against EMI
  • Supply voltage: 2.7 V to 5.5 V
  • Improved immunity against ambient light
  • Insensitive to supply voltage ripple and noise
