LA1245
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.
Features
Narrow-band signal meter
: Available as an automatic search-stop signal (also available as a wide-band signal
meter). Signal meter output = 1/2 frequency
±1.5kHz typ.
Local oscillation buffer-output
: Facilitates the design of electronic tuning systems and frequency representation.
OSC (with ALC)
: The oscillation output is stabilized at a low level (350mVrms) for a varactor diode,
and tracking error is minimized.
RF amplifier
: Excellent in usable sensitivity by incorporating low-noise transistors in cascade
circuit (45dB/m typ).
MIX
: Double balanced differential MIX prevents the influence of spurious radiation and
IF interferences (IF interference = 85dB typ).
Low noise
: Excellent in S/N for intermediate input (57dB typ).
Compensation for VCC fluctuation : Allows little gain fluctuation and little distortion fluctuation (8 to 16V).
Low shock noise
: Able to decrease the shock noise by selecting AGC time constant when changing
VCC-on and/or switching the mode.
