IR Remote Receiver 30KHz 45m 3-Pin

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 connected to a microprocessor for decoding. The TSOP341 is 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. They are immune to dimmed LCD backlighting and any fluorescent lamps. AGC3 and AGC5 may also suppress some data signals in case of continuous transmission. Between these three receiver types, the TSOP323.., TSOP343.. are preferred. Customers should initially try the TSOP323.., TSOP343.. in their design. This component has not been qualified according to automotive specifications.
