Description
The ยต 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.
