Monolithic Linear IC
LA1130
AM Tuner for Car Radio
Overview
The LA1130 is an IC developed for AM tuner systems in
car radio applications. It provides low-level local
oscillation so that it can be applied in varactor diode tuning
applications as well as µ tuning applications.
Package Dimensions
unit: mm
3020A-SIP16
[LA1130]
Functions
• RF amplification
• MIX
• OSC (with ALC)
• IF amplification
• Detection
• AGC (normal)
• RF wide-band AGC
• Others
SANYO: SIP16
Features
• Good space factor due to single-end package.
• Easy to design printed circuit pattern due to 3mm-pitch pin interval.
• Double-balanced type MIX : Improvement in IF interference, spurious interference.
• Normal AGC :
Less variation in detector output to input.
• RF wide-band AGC :
Improvement in cross modulation distortion, especially strong input characteristics in
varactor diode tuning applications because of low operating level (300mVrms).
• AGC drive output for FET : Possible to apply AGC to FET at input stage in varactor diode tuning applications.
• ALC at OSC stage :
Improvement in tracking error due to stabilized low-level (350mVrms) oscillation output
in varactor diode tuning applications.
• Reference voltage output : Possible to use 5.6V reference voltage for other bias (FET, etc.).
• VCC variation compensation : Less variation in gain, distortion, etc. (7.5 to 16V)
• Less ripple voltage :
Less modulation of carrier by supply voltage ripple.
• Low pop noise :
Possible to reduce pop noise at the time of VCC-on, mode-on by selecting AGC time
constant.
