Vishay Intertechnology Unveils New Series of Miniature IR Receivers for Remote Control Systems

Vishay Intertechnology, Inc. (NYSE: VSH) is broadening its optoelectronics portfolio with the release of a new series of miniature IR receivers for remote control systems that combine a PIN diode, preamplifier, and internal filter for PCM frequency in one ultra-thin package with a 1.3 mm top-view profile.

The design of the TSOP85...AP5 devices results in a high sensitivity-to-size ratio, with irradiance from 0.15 mW/sqm to 0.35 mW/sqm over wide angles of 75 degrees.

The devices released today are offered in four automatic gain control (AGC) versions. The TSOP852..AP5 is compatible with all common IR remote control data formats. The TSOP853..AP5 and TSOP854..AP5 suppress almost all spurious pulses from energy-saving fluorescent lamps. Offering excellent noise suppression, the TSOP855..AP5 is immune to dimmed LCD backlighting and any fluorescent lamps. In addition, the TSOP853..AP5 and TSOP855..AP5 are both compatible with short-burst codes.

The TSOP85...AP5 receivers offer low typical power consumption with a supply current of 0.35 mA typical at 3.3 V. The devices are insensitive to supply voltage and ripple noise and offer an improved immunity against ambient light. The devices' epoxy lens cap is designed as an IR filter.

The TSOP85...AP5 series was designed to fulfill the needs of industrial and consumer products where space is extremely limited but maximum performance is required. The devices are optimized for remote control and data transmission applications in small handheld electronics, such as notebook computers and digital still cameras, as well as ultra-thin LCD TVs.

The receivers offer a supply voltage range of 2.5 V to 5.5 V and operate over a carrier frequency of 36 kHz to 56 kHz. The devices offer a 35 m transmission distance and are pin-to-pin compatible with market standards. All devices are in accordance with RoHS 2002/95/EC and WEEE 2002/96/EC, and are halogen-free according to the IEC 61249-2-21 definition.
