Miniature IR receivers offer increased robustness to optical and RF emissions

03-06-2019 | Vishay | Subs & Systems

Vishay Intertechnology offers two new series of miniature IR receiver modules for IR remote control applications. Devices in the company's TSOP95xxx and TSOP96xxx series provide enhanced dark-ambient and disturbed-ambient sensitivity to infrared signals, greater suppression of RF noise, and good pulse-width accuracy.


The receivers are intended for IR remote control in televisions, set-top boxes, air conditioners, video projectors, cameras, audio systems, video game systems, and more. For the remote control function in these devices, the products offer improved robustness against disturbances such as IR emissions from CFL lamps and RF emissions from onboard WiFi antennas. Also, the modules' improved pulse-width accuracy enables lower bit error rates for almost any code, and the modules are insensitive to supply voltage variations and ripple noise.


To simplify designs, the receivers provide a photodetector, preamplifier circuit, and IR filter in a single four-pin epoxy Heimdall (TSOP95xxx) or Panhead (TSOP96xxx) package. The devices are offered with carrier frequencies from 30kHz to 56kHz and in five AGC versions for short and long burst codes. The receivers offer a low supply voltage from 2V to 3.6V and a typical supply current of 0.37mA. They are RoHS-compliant, halogen-free, and Vishay Green.
