T2525 Datasheet IR RECEIVER ASSP

Manufacturer: Atmel (now Microchip Technology)

General Description

The IC T2525 is a complete IR receiver for data communication that was developed and optimized for use in carrier-frequency-modulated transmission applications.

The IC offers highest sensitivity as well as highest suppression of noise from daylight and lamps.

The T2525 is available with broadest range of carrier frequencies (30, 33, 36, 37, 38, 40, 44, 56, 76 kHz) and 5 different noise suppression regulation types (standard, lamp, noise, short burst, data rate) covering requirements of high-end remote control solutions (please refer to selection guide available for T2525/ATA2526).
