Ordering number : EN595C Monolithic Linear IC LA1130 AM Tuner for Car Radio Overview Package Dimensions 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. 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.
