A new series of miniaturized, multifunctional surface-mount IR receiver modules that provide a variable supply voltage range from 2.7V to 5.5V was introduced by Vishay Intertechnology Inc.

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.

According to Vishay, the TSOP36xxx receiver modules are not only being specified for an unusually broad supply voltage range, but are also capable of operating with short-burst (>6 cycles/burst) transmission codes and data rates up to 4,000bps with seven standard carrier frequencies from 30kHz up to 56kHz.

Package doubles as IR filter

Integrated Automatic Gain Control (AGC) suppresses ambient light disturbances for reliable operation, and the modules' epoxy package doubles as an IR filter to further enhance immunity against ambient light. With metal shielding, devices in the TSOP36xxx series are also protected against electrical field disturbances.

The products 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 a good solution for multimedia applications.

Each module measures 5.3-by-7.2mm with a 2.35mm height profile. They are specified for an operating temperature range of -40C to 90C, and are TTL- and CMOS-compatible.
