PREAMPLIFIER FOR INFRARED REMOTE CONTROL
The information in this document is subject to change without notice.
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
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 k
TYP.)
