Fm If System Semicon Device

Being developed for FM IF System, LA1231 is a highly integrated circuit in which almost all functions are contained concerning the FM Tuner IF stage. The block diagram of equivalent circuit is shown below. Usual peripheral circuits are shown also in examples of application circuits. The IF Amplifier and limiter stages are composed of 6- stage double-end type Differential Amplifier which is superior on its AMR. The signal meter driving stage which is located in parallel therewith consists of a 3-stage level detector circuit and a drive circuit in order to extend the linear area.
