µ PC2807,2807A
PREAMPLIFIER FOR INFRARED REMOTE CONTROLLER
DESCRIPTION
The µ PC2807 and 2807A are semiconductors integrated circuit developed as preamplifiers for the receiver module of
infrared remote controllers. These preamplifiers can be directly connected to a PIN photodiode, and integrate a high-gain
first stage amplifier, limiter, bandpass filter, detector circuit, and waveform-shaping circuit on a single chip.
FEATURES
• Only PIN photodiode required as an external component.
• Following carrier frequencies (fO) selectable (five types):
µ PC2807 : fO = 32.7, 36.0, 36.7, 37.9 kHz
µ PC2807A : fO = 40.0 kHz
• Fixed trap frequency
fT = 54 kHz
• Active-low output
• Supplied in form of wafer
APPLICATION
• Receiver module of infrared remote controller

Function
Power pad. Apply a voltage of 5 V ± 10 %. Connect an external smoothing filter if noise on power line
is high.
GND pad (for output transistor)
GND pad (for circuits excluding output transistor)
Input pad. Internal impedance is 190 kΩ TYP. PIN photodiode can be directly connected.
Output pad. Open-collector output with pull-up resistor (22 kΩ TYP.) To connect pull-up resistor, use
resistor of 10 kΩ or higher.
BPF center frequency setting pads.
Connect pad corresponding to carrier frequency to be used to GND Note.
BPF output pad. Parameters such as voltage gain and BPF bandwidth can be tested.
Do not connect this pad to anything on final assembly.
Test and trimming pads. Do not connect these pads to anything.
Note Connect each of BPF center frequency setting pads as follows depending on the carrier frequency.
