ATA2526  
1. Description  
The IC ATA2526 is a complete IR receiver for data communication 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 ATA2526 is available with standard frequencies  
(33, 36, 37, 38, 40, 56 kHz) and 3 different noise suppression regulation types (stan-  
dard, lamp, short burst) covering requirements of different high-volume remote control  
solutions (please refer to selection guide available for ATA2525/ATA2526). The  
ATA2526 operates in a supply voltage range of 2.7V to 5.5V.  
The function of the ATA2526 can be described using the block diagram of Figure 1-1  
on page 2. The input stage meets 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. All 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 special features are used to adapt to the current application to secure best  
transmission quality.
