Vishay Upgrades 5-V Infrared Receiver Series to Offer 15 % Greater Sensitivity, 30 % Reduction in Operating Current, Broader 3-V to 5-V Power Supply Range, and Improved Pulse Width Accuracy and EMI and ESD Immunity
MALVERN, Pa. — Oct. 1, 2008 — Vishay Intertechnology (NYSE: VSH) today announced that it is upgrading the performance of its 5-V infrared receivers with a new-generation IC that increases sensitivity of the device by 15 % while improving pulse width accuracy.
The IC is one of the major determinants of performance in an IR receiver, along with the photo diode and the optical package itself. Sensitivity directly affects the range of a receiver, and is critically important in most IR receiver applications.
Further improvements resulting from the new IC include a 30 % reduction in device operating current; a broader power supply range of 3 V to 5 V; greatly enhanced immunity to EMI and ESD; and an improved battery saving mode.
Beginning October 2008, the new IC will become a standard feature of all Vishay 5-V infrared receivers in both the Minicast and molded through-hole packages. The upgraded devices can be identified on the Vishay Web site by their part numbers beginning with TSOP2X.., TSOP4X.., TSOP58X.., and TSOP59X.., and by the word "New" in the datasheet title.
A complete listing of Vishay's IR receiver products is available at http://www.vishay.com/ir-receiver-modules/.
No price increase is planned for the upgraded receivers, which effectively translates into an improved price / performance device for Vishay customers. Samples of the devices are available now. Production quantities will be available in October 2008, with lead times of four weeks for larger orders.
