Monolithic Linear IC  
LA1245  
AM Electronic Tuner  
Overview  
Package Dimensions  
LA1245 is a high performance IC to be used as an AM  
unit : mm  
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.  
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  
• OSC (with ALC)  
: 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.  
• RF amplifier  
• MIX  
: 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).  
• Low noise  
: Excellent in S/N for intermediate input (57dB typ).  
• Compensation for V fluctuation : Allows little gain fluctuation and little distoriton fluctuation (8 to 16 V).  
CC  
• Low shock noise  
: Able to decrease the shock noise by selecting AGC time constant when changing  
-on and/or switching the mode.
