LV24230LS
Bi-CMOS LSI
Compact Portable Equipment
1-Chip FM Tuner IC
Overview
The LV24230LS is an I2C-controlled single-chip FM tuner IC that integrates external components which are necessary for
tuning in a compact VQLP package with dimensions of only 3.5×3.5×0.85mm3. Equipped with a state machine, the
LV24230LS has the capability to perform automatic tuning/seek and dissipates less power than conventional
LV24000series tuner ICs.
