ATA2525 IR Receiver ASSP DATASHEET Features ● No external components except PIN diode ● Supply-voltage range: 4.5V to 5.5V ● High sensitivity due to automatic sensitivity adaption (AGC) and automatic strong signal adaption (ATC) ● High immunity against disturbances from daylight and lamps ● Small size and innovative pad layout ● Available for carrier frequencies between 33kHz to 40kHz; adjusted by zener diode fusing ● TTL and CMOS compatible ● Suitable minimum burst length ≥ 10 pulses/burst Applications ● Home entertainment applications ● Home appliances ● Remote control equipment

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...

Absolute Maximum Ratings Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
