µPC2800A

PREAMPLIFIER FOR INFRARED REMOTE CONTROL

DESCRIPTION

The µPC2800A 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^Otrimming

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 disturbance from external light

Open-collector output

Open-collector output (active low) with pull-up resistor (33 kΩ TYP.)
