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 (six types):

µPC2807

: fO

= 32.7, 36.0, 36.7, 37.9, 56.7 kHz

µ PC2807A : fO = 40.0 kHz

• Fixed trap frequency

fT

= 54 kHz (when carrier frequency is 56.7 kHz, trap frequency is 76 kHz)

• Active-low output

• Supplied in form of wafer

APPLICATION

• Receiver module of infrared remote controller
