Description
The IC U2538B is a complete IR receiver for data communication. The useful input
signals are separated by a special input circuit and amplified by a gain-controlled
amplifier. The bandpass filter suppresses the off-band signals. The signal detector,
consisting of a demodulator, an integrator and a Schmitt trigger, forms the input signal
to an output pulse that can be interfaced to a microcomputer. The AGC and the ATC
circuit control the receiver's sensitivity, making it insensitive to ambient light sources.
