The VSOP98260, touted by Vishay as the industry's first remote control code learning IC to integrate signal detection and processing into one component, is optimized for universal remote controllers. The IC amplifies and shapes the signal received by the infrared emitter already present in the devices, and can be used in tablet PCs and smartphones that are enabled with an infrared emitter. The IC can receive any carrier frequency from 20 kHz to 60 kHz, and operates on a supply voltage from 2.0 V to 3.6 V and a supply current of 0.6 mA to 0.9 mA. Packaged in 2 mm by 2 mm QFN with a height of 0.7 mm, the RoHS-compliant device operates over a temperature range of − 25 °C to + 85 °C and is compliant to WEEE 2002/96/EC. Samples and production quantities of the VSOP98260 IC are available now, with a lead time of six weeks for large orders. Pricing for U.S. delivery starts at $0.40 each/3,000.
