Vishay Intertechnology Inc. rolls a new series of miniature IR receivers for remote control systems.

The devices combine a PIN diode, preamplifier, and internal filter for PCM frequency in a 1.3mm profile-package. The design of the TSOP85...AP5 devices results in a high sensitivity-to-size ratio, with irradiance from 0.15mW/sqm to 0.35mW/sqm over angles up to 75 degrees.

There are four AGC versions of the receivers: the TSOP852..AP5 is compatible with all common IR remote control data formats; TSOP853..AP5 and TSOP854..AP5 suppress almost all spurious pulses from energy-saving fluorescent lamps; and TSOP855..AP5 is immune to dimmed LCD backlighting and any fluorescent lamps. Also, TSOP853..AP5 and TSOP855..AP5 are both compatible with short-burst codes.

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. They are designed for industrial and consumer products where space is limited but maximum performance is required, including remote control and data transmission applications in small handheld electronics, notebook computers, DSCs and LCD TVs.

The receivers offer a supply voltage range of 2.5V to 5.5V and operate over a carrier frequency of 36kHz to 56kHz. They offer a 35m 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.

Samples and production quantities of the TSOP85...AP5 receivers are available now, with lead times of four to six weeks for large orders.
