Vishay Intertechnology Releases Ultra-Low-Profile IR Receivers for Remote Control With Height of 0.8 mm
Surface-Mount Receivers Offer a Phenomenally Wide Angle of Sensitivity of 150° and a Receiving Distance of 40 Meters
MALVERN, Pa. — April 16, 2012 — Vishay Intertechnology, Inc. (VSH: NYSE) today 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 (which includes the TSOP572.., TSOP573.., TSOP574.., and TSOP575.. devices) combine an ultra-low height of 0.8 mm, one of the lowest on the market, with a phenomenally wide angle of sensitivity of 150°. The receivers feature Vishay’s hallmark sensitivity, resulting in a receiving distance of 40 m.
Flat panel LCD and plasma TV displays continue to get thinner, which means that the components inside them need to get thinner as well, without compromising performance. But it’s not just TV sets that need low-profile infrared receivers. Set-top boxes, stereo systems, and in-room air-conditioners also need to accommodate IR receivers within a highly constrained area.
Vishay’s TSOP57x IR receiver responds to this need with a height of just 0.8 mm—thinner than a house key. The new 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 which 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 940 nm, and are available in modulation frequencies of 36 kHz, 38 kHz, 40 kHz, and 56 kHz.
The devices feature an environmentally friendly “green” construction compliant to RoHS Directive 2011/65/EU and in accordance to WEEE 2002/96/EC.
