LM3820 AM Radio System
General Description
The LM3820 is a 3-stage AM radio IC consisting of an RF
amplifier oscillator mixer IF amplifier AGC detector and
zener regulator
The device was originally designed for use in slug-tuned
auto radio applications but is also suitable for capacitor-
tuned portable radios
The LM3820 is an improved replacement for the LM1820
