Overview
The LV3327PV is electronic volume LSI for the volume adjustment of the portable sound equipment usage.
Features
The mixing function is installed, and it is suitable for PND (personal navigation device) as the usage.
It is possible to output it by allocating one system in the audio guidance among four input systems, and mixing other
signals from the speaker output with the audio guidance by the microcomputer control.
Because the volume step resolution is 0.5dB step, the volume can be made to fine-tune.
The loudness function is installed.
Functions
Input switching : 4 input systems (Independent control is possible.)
Volumn control : +10dB to -79.5dB(0.5dB steps)/-
Loudness control :
Taps are output starting at the -32dB position of the ladder resistor and a loudness function implemented with
external capacitor and resistor components.
Output gain control : 0dB or +6dB select
Mixing function
Output switching :
2 outputs (Each Lch output, Rch output, and Lch/Rch mixing output can be selected).
Each control is done by the sirial data input. I2C
