LM1868 AM/FM Radio System
General Description
The combination of the LM1868 and an FM tuner will pro-
vide all the necessary functions for a 0.5 watt AM/FM radio.
Included in the LM 1868 are the audio power amplifier, FM
IF and detector, and the AM converter, IF, and detector.
The device is suitable for both line operated and 9V battery
applications.
Features
Y
DC selection of AM/FM mode
Y
Regulated supply
Y
Audio amplifier bandwidth decreased in AM mode,
reducing amplifier noise in the AM band
Y
AM converter AGC for excellent overload
characteristics
Y
Low current internal AM detector for low tweet radiation
