CXA1511L/M
Preamplifier for Remote Control Signal Reception
Description
The CXA1511L/M is a bipolar IC used for
preamplifiers that receive signals in infrared remote
control systems. These ICs consist of a first-stage
amplifier, limiter amplifier, band-pass filter, band
elimination filter, signal waveform detection circuit
and waveform shaping circuit.
8 pin SIP (Plastic)
8 pin SOP (Plastic)
Features
Low power consumption (VCC = 5V, 9mW typ.)
Low supply voltage (VCC = 5V)
Filters (center frequency can be varied through
external resistor: fo = 30kHz to 60kHz, 40kHz typ.)
Elimination of inductors prevents magnetic field
inductance interference.
Optical reception diode can be coupled directly.
Collector output (pull-up resistor, TTL and CMOS
can be connected directly)
Applications
TVs, VCRs, audio equipment

Connect a resistor and
capacitor in series to GND,
and set the frequency
response and gain of "Head
Amp".
When the resistor is large
40µA and the capacitor small, the
gain is small.
When the capacitor is large,
8k sensitivity decreases in
relation to the transient
response.

Connect a detection capacitor
to GND.
When the capacitor is large,
sensitivity decreases in relation
to the mean value detection
and transient response.
When the capacitor is small,
fluctuation of the peak detection
and output pulse width
increases.
The capacitor in usage is
0.01µF (typ.). Set output pulse
width fluctuation and noise
elimination characteristics to be
optimum.
GND pin.
Adopt a pattern design that will
allow external parts to be
located as closely as possible
to this pin. Ground them all at
the same point. The transport
distance and noise elimination
characteristics are greatly
influenced by the pattern design
surrounding the GND.
Connect a resistor to the
power supply.
Set the center frequency of
the built-in BPF.
See "External resistor at
Pin 5 vs. Center frequency
response" on Page 6.
