DESCRIPTION

The TSOP332.. and TSOP334.. series are miniaturized IR

receiver modules for infrared remote control systems. A PIN

diode and a preamplifier are assembled on lead frame, the

epoxy package contains an IR filter.

The demodulated output signal can be directly connected to

a microprocessor for decoding.

The TSOP334.. series devices are optimized to suppress

almost all spurious pulses from energy saving lamps like

CFLs. The AGC4 used in the TSOP334.. may suppress

some data signals. The TSOP332.. series are provided

primarily for compatibility with old AGC2 designs. New

designs should prefer the TSOP334.. series containing the

newer AGC4.

These components have not been qualified according to

automotive specifications.
