Preamplifier for IR Remote Control
Description
The IC U2535B is a complete IR receiver for data com-
munication. The PIN photodiode converts the transmitted
IR telegram into electronic input signals. This is sepa-
rated by a special input circuit. The characteristics (filter,
gain) of the following amplifier are determined by exter-
nal components. The signal detector, consisting of a
comparator, an integrator and a Schmitt trigger, forms the
input signal to an output pulse that can be interfaced to a
microcomputer.
Features
Low current requirement (typical 260 A/ 12 V)
Carrier frequencies 20 to 100 kHz
Supply voltages:
5 or 7 to 16 V with internal stabilization
Filter characteristics and gain are specified by few
external components
Demodulator with Schmitt trigger
Open collector output
Applications
Keyless entry
Remote control
Wireless data transfer
