... PREAMPLIFIER FOR INFRARED REMOTE CONTROL DESCRIPTION The 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. ...

... Keep the wiring length between the PIN photodiode and pin 8 as short as possible. • Keep the signal lines of pins 2 and 6 as far away as possible from those of pins 7 and 8. • Commonly ground the anode of the PIN photodiode and the external capacitor connected to pin 7. Separate the GND and power GND of pin 6 from these. ...
