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 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.
