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 high-volume remote
control solutions (please refer to selection guide available for Atmel ATA2525/ATA2526). The Atmel ATA2526 operates in a
supply voltage range of 2.7V to 5.5V.
The function of the Atmel ATA2526 can be described using the block diagram of Figure 1-1. The input stage has two main
functions. First it provides a suitable bias voltage for the PIN diode. Secondly the pulsed photo-current signals are
transformed into a voltage by a special circuit which is optimized for low noise applications. After amplification by a controlled
gain amplifier (CGA) the signals have to pass a tuned integrated narrow bandpass filter with a center frequency f0 which is
equivalent to the chosen carrier frequency of the input signal. The demodulator is used first to convert the input burst signal
to a digital envelope output pulse and to evaluate the signal information quality, i.e., unwanted pulses will be suppressed at
the output pin. This is done by means of an integrated dynamic feedback circuit which varies the gain as a function of the
present environmental conditions (ambient light, modulated lamps etc.). Other features can be used to adapt the device to
the individual application to ensure best transmission quality.

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.
