Ordering number : ENA1879A 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.

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. Reference data Parameter Symbol VDD power rise time Trise VDD voltage when power ON reset is canceled Vpor Conditions 0V → 2V power rise time Min Typ Max Unit 30 - - μsec - 2 - V (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. No.A1879-10/11 LV3327PV ON Semiconductor and the ON logo are registered trademarks of Semiconductor Components Industries, LLC (SCILLC).
