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.

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.).

•VCCvariation 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.
