VISHAY TSOP34138

These products are miniaturized receivers for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame, the epoxy package contains an IR filter. The demodulated output signal can be directly connected to a microprocessor for decoding. The TSOP323.., TSOP343..series devices are optimized to suppress almost all spurious pulses from energy saving lamps like CFLs. AGC3 may also suppress some data signals if continuously transmitted. The TSOP321.., TSOP341.. series are provided primarily for compatibility with old AGC1 designs. New designs should prefer the TSOP323.., TSOP343.. series containing the newer AGC3. The TSOP325.., TSOP345.. series contain a very robust AGC5. This series should only be used for critically noisy environments. These components have not been qualified according to automotive specifications.
