DATA SHEET
BiCMOS INTEGRATED CIRCUIT
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
