Default Digital Audio Pot

Hello All,


I want to use a digital audio pot in my design and i think the CS3310 is quite impressive.
But i heard/read some where, and i do not know anymore, that the perfomrnace can be improved.
Either by using it in differential mode or in a feedback path.

Does any one know ?????


grtz,

Simon

TI has a dropin replacement called PGA2311 with a better performance.

Tha PGA2310 is also a dropin replacement but it needs higher supplyvoltage : +/-15V.

You can get the PGA2311 or PGA2310 in small quantity at www.digikey.com

Or if you have ARROW located in your country try them but be prepared to take a minimum of ~ 250 - 1000pcs.

SORRY ... You can get up to 3 samples of the PGA2310 or the PGA2311 direct from TI.

How are you planning to control the device?

I share some code for an AVR which was shared with me at:
