IR Receivers Have Very High Sensitivity-To-Size Ratio

Jan 23, 2009 10:18 AM, MD&D News Staff

A new series of ultra-miniature SMD IR receivers for remote-control systems offers the industry’s best sensitivity-to-size ratio, according to Vishay Intertechnologies. The devices feature a typical irradiance of 0.15 mW/m2, a typical supply current of only 0.35 mA at 3.3 V, and a 3.0-mm profile in side view.

The devices come in three automatic gain control versions. The TSOP752xx is compatible with all common IR remote-control data formats. The TSOP753xx and TSOP754xx suppress almost all spurious pulses from energy-saving fluorescent lamps, including dimmed LCD backlighting, and are compatible with short-burst or long-burst codes, respectively.

The receivers are optimized for remote-control and data-transmission applications in small handheld electronics, such as notebook computers, digicams, and portable music and video players, as well as set-top boxes, thin LCD TVs, game controllers, navigation systems, and USB-TV. The receivers work at supply voltages of 2.5 to 5.5 V and operate over a carrier frequency of 30 kHz to 56 kHz.

All devices comply with RoHS 2002/95/EC and WEEE 2002/96/EC. Samples and production quantities of the TSOP75xxx receivers are available now, with lead times of six weeks for large orders. Pricing begins at $1.50 per piece in small quantities.
