Description

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.

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
