Description

The Atmel® IC T2526 is a complete IR receiver for data communication developed and optimized for use in carrierfrequency-modulated transmission applications. The IC offers highest sensitivity as well as highest suppression of noise from daylight and lamps. The Atmel T2526 is available with broadest range of frequencies (30, 33, 36, 37, 38, 40, 44, 56kHz) and 3 different noise suppression regulation types (standard, lamp, short burst) covering requirements of high-end remote control solutions (please refer to selection guide available for Atmel T2525/T2526). Atmel The T2526 operates in a supply voltage range of 2.7V to 5.5V.

Features
