Product Summary

The TSOP34838 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 TSOP34838 is compatible with all common IR remote control data formats. The TSOP34838 is optimized to suppress almost all spurious pulses from energy saving fluorescent lamps but will also suppress some data signals. This component has not been qualified according to automotive specifications.
