Overview
LA1245 is a high performance IC to be used as an AM
electronic tuner. It provides an automatic search-stop
signal, local oscillator buffer-output, and the low level
local oscillation, as well as providing all other functions
required of an AM tuner. Moreover, the stable local
oscillation from LW to SW facilitates the use of many
band.
Functions
RF amplifier
MIX
OSC (with ALC) Detection
IF amplifier
AGC
Local oscillation buffer-output
Signal meter driving output (also used as an automatic
search stop-signal)
etc.

SANYO: DIP20S
: Available as an automatic search-stop signal (also available as a wide-band signal
meter). Signal meter output=1/2 frequency ±1.5kHz typ.
: Facilitates the design of electronic tuning systems and frequency representation.
: The oscillation output is stabilized at a low level (350 mVrms) for a varactor
diode, and tracking error is minimized.
: Excellent in usable sensitivity by incorporating low-noise transistors in cascode
circuit (45dB/m typ).
: Double balanced differential MIX prevents the influence of spurious radiation and
IF interferences (IF interference = 85dB typ).
: Excellent in S/N for intermediate input (57dB typ).
: Allows little gain fluctuation and little distoriton fluctuation (8 to 16 V).
: Able to decrease the shock noise by selecting AGC time constant when changing
V
CC
-on and/or switching the mode.
