DESCRIPTION

The TSOP373..H, TSOP375..H series are miniaturized

receiver modules for infrared remote control systems. A PIN

diode and a preamplifier are assembled on a PCB, the

epoxy lens cap contains an IR filter. The demodulated

output signal can be directly connected to a microprocessor

for decoding.

The TSOP373..H 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.

New designs should prefer the TSOP373..H series. The

TSOP375..H 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.

FEATUES
