The TSOP312.. series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. TSOP312.. is the stan- dard IR remote control receiver series for 3 V supply voltage, supporting all major transmission codes.
The TSOP312 series are miniaturized infrared receiver modules designed for remote‑control systems. Each device integrates a photodiode and preamplifier in a single package with an internal filter to reject ambient light and electrical noise. The demodulated output is TTL/CMOS compatible and active‑low.
