LV3327PV
Bi-CMOS LSI
Electronic Volume IC
http://onsemi.com
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

Usage Cautions
(1) Request to send the initial data at power ON
• Though the circuit initializing the IC inside at power ON is incorporated, be sure to send data to all sub-address as the
initial data at power ON.
• At power ON, muting or other measures must be taken externally till the data is set.

(2) Data is switched by standing up about the ACK clock of the data setting bit.
(3) The auto increment function is moved in the SUB address as follows.
…=>DATA_1=>DATA_2=>DATA_5=>DATA_6=>DATA_26=>DATA_29=>DATA_30=>DATA_31=>DATA
_1=>…
(4) As for the mixing function, half the value in which the Lch volume output and the Rch volume output are added is
output. (Lch+Rch)/2. Please set +6dB if necessary in the output steps.
