UPC2800A - PREAMPLIFIER

Datasheet Summary

Description

The µ PC2800A is a receiver preamplifier for infrared remote control systems.

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 output pull-up resistor and power supply filter resistor Only low external capacitance required.
  • ABLC (Automatic Bias Level Control) circuit Controls fluctuation of bias level cause by distu.
