For my next uprade to my BoSoZ (it's been operational for 3 years and i'm still poking around with it) I want to add a digital volume control. I've got some experience with BASIC stamps and i'm looking for some sort of starting point for getting the stamp to control the PGA2310. Thanks.

![]() The PGA2310 is an almost complete preamp, with internal opamp. I wouldn't use it with BoSoZ, I would use it as it is and throw away the BoSoZ If you want a new volume controll for the BoSoZ i would build something with relays. Like this: Constant impedance relay-resistor logarithmic attenuator /Freddie |

Haha, nope, not the answer I was looking for but good to know none-the-less. I knew it had a buffer...didn't know it could be considered to be a full on preamp.
Oh well, on the plus side, i've got all the parts to make this work (free samples) and I always welcome the experience. Also, it seems like a good (read inexpensive) alternative when I switch over to fully balanced (daisy-chained). |

Link is broken, but from my previous searches on DIY audio for info on the chip, I know what site you're linking too. If it's your site, congrats on being hit #2 on google under 'pga2310'
Very informative.Right now i'm flipping through the datasheet, BASIC stamp manual and looking at the sample code from that site. |
