Vishay Intertechnology Launches VSOP98260 Remote Control Code Learning IC

Vishay Intertechnology VSOP98260 remote control code learning IC

Vishay Intertechnology announced the VSOP98260 remote control code learning IC. The chip simplifies the code learning process by amplifying and shaping the signal received by the infrared emitter already present in these devices. It can also be used in tablet PCs and smartphones that are enabled with an infrared emitter. The Vishay VSOP98260 IC is available now, with a lead time of six weeks for large orders. Prices start at $0.40 per unit in 3,000-piece (one reel) quantities.

The Vishay VSOP98260 is optimized for universal remote controllers. It is the first chip to integrate signal detection and processing into a single component. Before the VSOP98260, signal detection and processing functions for code learning in universal control devices required discrete solutions. By combining these functions into one component, the VSOP98260 simplifies designs in these devices, saves space and reduces overall costs.

The output from the VSOP98260 accurately corresponds to the carrier frequency and data burst length of the input signal. It is also immune to noise from other light sources such as compact fluorescent lamps.

The VSOP98260 can receive any carrier frequency from 20 kHz to 60 kHz, and it 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. The IC is packaged in a small 2 mm by 2 mm QFN package with a low height of 0.7 mm. The VSOP98260 is RoHS and WEEE 2002/96/EC compliant. It is free of halogens, and is compatible with lead (Pb)-free soldering. The IC operates over a temperature range of – 25° C to + 85° C.
