Récepteur IR, TSOP39438TR1, 38kHz

The Vishay miniaturized IR receiver modules for infrared remote control systems. Two PIN diodes and a preamplifier are assembled on a lead frame, the epoxy package contains an IR filter. The demodulated output signal can be directly connected to digital circuitry for decoding. This series is optimized to suppress almost all spurious pulses from energy saving lamps like CFLs.

Low supply current
Photo detector and preamplifier in one package
Internal filter for PCM frequency
Insensitive to supply voltage ripple and noise
Improved immunity against ambient light
Two lenses for high sensitivity
