Product Summary

The TSOP1238 is a miniaturized receiver for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame, the epoxy package acts as an IR filter. The demodulated output signal can be directly decoded by a microprocessor. The TSOP1238 is compatible with all common IR remote control data formats. This component TSOP1238 has not been qualified according to automotive specifications.
