U2535B-FP Datasheet

Preamplifier for IR Remote Control


The IC U2535B is a complete IR receiver for data communication. The PIN photodiode converts the transmitted IR telegram into electronic input signals. This is separated by a special input circuit. The characteristics (filter,gain) of the following amplifier are determined by external components.

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
