A series of miniaturised, multi-functioned SMD IR receiver modules that provides a variable supply voltage range from 2.7 to 5.5 has been announced by Vishay.
Devices in the new TSOP36xxx series combine a photo detector and preamplifier in a single, highly integrated package to enable the design of space-saving and reliable remote control systems.
In addition to being specified for an unusually broad supply voltage range, the modules are capable of operating with short-burst (³6 cycles/burst) transmission codes and data rates up to 4000 bit/s with seven standard carrier frequencies from 30 to 56 kHz.
Integrated automatic gain control suppresses ambient light disturbances for reliable operation, and the modules' epoxy package doubles as an IR filter.
With metal shielding, devices in the TSOP36xxx series are also protected against electrical field disturbances.
The modules also feature low power consumption, a low active output and an internal band filter that allows PCM frequency operation. A demodulated output signal that can be decoded directly by a microprocessor makes these devices suitable for multimedia applications.
