Vishay TSOP94638, 38kHz IR Receiver, 950nm, 35m Range

The Vishay miniaturized IR receiver modules for infrared remote control systems. These series provide improvements in sensitivity to remote control signals in dark ambient as well as in sensitivity in the presence of optical disturbances e.g. from CFLs. The devices contain a PIN diode and a preamplifier assembled on a lead frame. The epoxy package contains an IR filter. The demodulated output signal can be directly connected to a microprocessor for decoding.

Very 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 optical noise
