Monolithic Linear IC
LA1135, 1135M
AM Tuner System for
Car Radios and Home Stereos
Overview
The LA1135 is a high-performance AM electronic tuner IC that
is greatly improved in cross modulation characteristics. It is
especially suited for use in car radio and home stereo (antenna:
loop) applications.

Features
. _{Excellent cross modulation characteristics: Meets the}
requirements for preventing not only adjacent-channel
interference but also interference caused by all channels
. within broadcast band.
Narrow-band signal meter output: Usable as auto search stop
. signal. Has linearity up to 80 dBµ.
Local oscillation buffer output: Facilitates designing of
. electronic tuner system, frequency display, etc.
OSC (with ALC): Improves tracking error because
oscillation output is stabilized at a low level (380 mVrms)
. for varactor diode.
MIX: Double-balanced differential MIX meeting the
requirements for preventing spurious interference, IF
. interference.
Good characteristics at high input: 130 dBµ input
f_m = 400 Hz 80% mod THD = 0.4% typ
. _{Low noise: Good S/N at medium input (56 dB typ)}
. _{Usable sensitivity: (S/N = 20 dB input): 25 dBµ (2SK315}
. ^{IDSS = 11mA)}
V_CC variation compensation: Less variation in gain,
. distortion: 8 to 12 V
Reduced pop noise: Capable of reducing pop noise at the
time of V_CC ON, mode select by adjusting AGC time
constant.
