hi, I am using PGA2310 audio control for my design.... Can i gave +/- 12V to Analog power Supply??? In datasheet and EVM , input to analog power supply is 15V only... If i give 12V, is there any impact ??

    Hi, Lakshmi,

    The biggest thing you will lose is output swing. With +/-12V supplies, you won't be able to get as much output swing as with +/-15V supplies.

    The data sheet actually says you can run with as low as +/-4.5V supplies.

    Hello Lakshmi,

    As mentioned by d2, when using power supplies of +/-12V, the input and output signal range will be limited to +/-10.5V.   The datasheet provides a few specifications of THD+N for different amplitude signals.  In the case where the user amplifies a signal close to the swing limit of  +/-10.5V ,  the resulting output signal  may see a slight increase in distortion.

    Best Regards,

    Luis
