Overview

DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUITS µ PC2800A PREAMPLIFIER FOR INFRARED REMOTE CONTROL DESCRIPTION The µ PC2800A is a receiver preamplifier for infrared remote control systems.
It can be directly connected to a PIN photodiode and integrates a high-gain first-stage amplifier, limiter, bandpass filter, detection circuit, and waveform shaping circuit to provide a receiver preamplifier on a single chip.
FEATURES • High reliability due to high-frequency lighting fluorescent lamp Internal trap circuit • Internal bandpass filter Central frequency variable by external resistor: f O = 30 to 80 kHz Few variation of central frequency thanks to f O trimming • Low external components Intern...
