DESCRIPTION
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 acts as an IR filter.
The demodulated output signal can be directly decoded by a microprocessor. The TSOP321.., TSOP341.. are legacy products, compatible with all common IR remote control data formats. The TSOP323.., TSOP343.. are optimized to better suppress spurious pulses from energy saving fluorescent lamps. The TSOP325.., TSOP345.. have an excellent noise suppression. It is immune to dimmed LCD backlighting and any fluorescent lamps. AGC3 and AGC5 may also suppress some data signals in case of continuous transmission.
