Next-generation miniature IR receivers provide improved sensitivity and noise suppression

Vishay Intertechnology has introduced the next generation of the company's miniature IR receiver modules for IR remote control applications. Devices in the company's TSOP11xxx, TSOP12xxx, TSOP13xxx, TSOP14xxx, and TSOP18xxx families produce both improved dark-ambient and disturbed-ambient sensitivity to infrared signals, and better suppression of RF noise. The devices' great pulse-width accuracy makes them ideal for codes requiring even the tightest pulse-width specifications, such as SIRCS and RCMM. The receivers are designed for IR remote control in televisions, STBs, air conditioners, audio systems, video game systems, video projectors, cameras, and more. For the remote control function in these products, the devices offer increased robustness against disturbances such as IR emissions from CFL lamps and RF emissions from on-board Wi-Fi antennas. Also, the modules' enhanced pulse-width accuracy enables lower bit error rates for almost any code, and the devices are insensitive to supply voltage variations and ripple noise. All receivers feature a supply voltage from 2.5V to 5.5V and low supply current, and they are RoHS-compliant, halogen-free, and Vishay Green.
