SMD IR Receivers

The TSOP52xxx family of IR receivers is designed for use in remote controls for automotive keyless entry systems, set-top boxes, camcorders, cameras, televisions, car stereos, and portable audio equipment. Devices in the series combine a photodetector and preamplifier in a package that can be mounted in either a top-view or side-view orientation to printed circuit boards. With a footprint of just 7.5 ý 5.3 mm and a 4-mm height profile, the compact devices allow savings on component costs by incorporating a single receiver module in a variety of product designs, as well as saving space wherever they are used.

In addition to their small size and extended distance range, devices conserve battery life by consuming minimal powerýtypically 6 mW when operating from a 4.5-V to 5.5-V supply voltage. Enhanced automatic gain control circuitry suppresses interference from sunlight, energy-saving lamps, and other light disturbances, while an external metal shield protects against EMI. Additional features include an internal band filter for PCM frequency operation, and TTL and CMOS compatibility.

To further simplify designs, devices in the series have a demodulated output signal that can be directly decoded by a microprocessor. The devices support all major transmission codes and are available with carrier frequencies of 30, 33, 36, 36.7, 38, 40, and 56 kHz.

Samples of the TSOP52xxx series are available now. Pricing in l00,000-piece quantities starts at $80/100 pieces.
