IR receivers for remote control only 0.8mm high, feature an angle of sensitivity of 150 degrees

April 17, 2012 // By Julien Happich
Vishay Intertechnology broadens its optoelectronics portfolio with the introduction of remote control receivers with the industry's best combination of size and angle of sensitivity.

Devices in the new TSOP57x series combine an ultra-low height of 0.8 mm, one of the lowest on the market, with a wide angle of sensitivity of 150°. The receivers' high sensitivity enable a receiving distance of 40m. The TSOP57x IR receivers have no lens, yet they provide on-axis sensitivity equal to any surface-mount receiver on the market. At an off-axis angle of 45°, the receivers' sensitivity is much better than devices with a lens, retaining 85 % of their on-axis sensitivity. Because remote control receivers are placed behind cosmetic windows that typically absorb some infrared light, this high sensitivity allows the TSOP57x series to outperform other surface-mount receivers on the market.


The receivers feature Vishay's intelligent automatic gain control (AGC), providing the industry's best noise suppression in versions that include AGC2, -3, -4, and -5. They have peak sensitivity of 940nm and are available in modulation frequencies of 36, 38, 40, and 56kHz
