UPC2800A PREAMPLIFIER

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 ch.

UPC2800A 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 Internal
