Description The Atmel® IC ATA2526 is a complete IR receiver for data communication that has been developed and optimized for use in carrier-frequency-modulated transmission applications. The IC combines small size with high sensitivity suppression of noise as caused by daylight and lamps. An innovative and patented pad layout offers unique flexibility for IR receiver module assembly. The Atmel ATA2526 is available with standard frequencies (33, 36, 37, 38, 40, 56kHz) and 3 different noise suppression regulation types (standard, lamp, short burst), thus covering the requirements of different...
