LV24100LP
Overview
Bi-CMOS IC
FM and AM Tuner IC for Small Portable Equipment
The LV24100LP is an innovative FM/AM tuner IC that is capable of configuring an FM/AM radio with just one external
component. Since all the FM/AM radio functions are incorporated into a compact VQLP package with dimensions of
only 5mm×5mm×0.8mm, this IC can easily incorporate FM/AM tuner function into mobile phones, PDA, MP3 player
and other small mobile sets where space is always at a premium.
