LV24030LP Datasheet, PDF (3/14 Pages) Sanyo Semicon Device – Bi-CMOS IC FM Tuner IC for Small Portable Equipment

LV24030LP
Operating Characteristics at Ta=25°C, VCC=3.0V, VDD=3.0V, Soft Mute/Soft Stereo=off, with the specified test circuit.
Output level setting is for the maximum output setting by setting Bit 4 and Bit 5 (Audio output level bits) of Address
04h of the control register map to “1” respectively. In other cases, the IF_BW set Bit value is when the value has been
set to 65% of the IF_OSC set Bit value.
(Register setting for IF_OSC set =140kHz and IF_BW=140kHz*0.65)
