Description  
The IC T2525 is a complete IR receiver for data communication developed and opti-  
mized for use in carrier-frequency-modulated transmission applications. Its function  
can be described using the block diagram (see Figure 1). 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 to convert the input burst signal into 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 environ-  
mental condition (ambient light, modulated lamps etc.). Other special features are  
used to adapt to the current application to secure best transmission quality. The  
T2525 operates in a supply-voltage range of 4.5 V to 5.5 V.
