Check Digi key. You can always blank 6 channels.
Looking for a 2-channel high end volume control
I am working on a balanced design and I need a gain control with two channels. I currently am considering the Cirrus Logic CS3308/18. Details here: https://www.cirrus.com/products/cs3308-18/
However, unfortunately, the Cirrus is an 8-channel gain control and they apparently do not have a 2-channel version of this chip.
Is there a chip of comparable quality that can simultaneously perform gain control on two channels?

I've done a fair bit of research into this, there are a few available... the TI range is listed here. I think Maxim might do some as well. The advantage of IC volume controls is that they track well, are cheap and small. The audio performance is not stellar though and THD+N can be better with a 10K pot. For real 'high end' it's hard to beat an R2R log stepped attenuator but you'll have to design, build and find a way of controlling that yourself - there are some DIY blogs out there. I use a 500Ω 128 step R2R attenuator in my preamp which measures -121dB THD+N (including the amplification stages) that's 10-15dB quieter than the best TI chip on its own. I know not many here like measurements but noise is noise. |

Have you checked what Khozmo offers? They sell stepped attenuators with lots of options. A bit pricey but looks like a quality product.https://khozmo.com/ BillWojo |
