DESCRIPTION

The TSOP312.., TSOP314..series are miniaturized IR receiver modules for infrared remote control systems. A PIN diode and a preamplifier are assembled on a leadframe, the epoxy package contains an IR filter.

The demodulated output signal can be directly connected to a microprocessor for decoding.

The TSOP312.., TSOP314.. are optimized to suppress almost all spurious pulses from energy saving lamps like CFLs. The AGC4 used in the TSOP314.. may suppress some data signals. The TSOP312.. is a legacy product for all common IR remote control data formats. Between these two receiver types, the TSOP314.. is preferred. Customers should initially try the TSOP314.. in their design.

These components have not been qualified according to automotive specifications.
