Description
The Atmel® IC ATA2525 is a complete IR receiver for data communication that was developed and optimized for use in carrier-frequency-modulated transmission applications. The IC combines small size with high sensitivity as well as high suppression of noise from daylight and lamps. An innovative and patented pad layout offers unique flexibility for assembly of IR receiver modules. The Atmel ATA2525 is available with standard carrier frequencies (33, 36, 37, 38, 40kHz) and 3 different noise suppression regulation types (standard, lamp, noise) covering requirements of different high-volume remote control solutions (please refer to selection guide available for Atmel ATA2525/ATA2526). The Atmel ATA2525 operates in a supply voltage range of 4.5V to 5.5V.
