[sdiy] Audio quality switch chips??

[Rutger Vlek]

+1 for the DG range.

I'm using DG408, DG412, DG413 and DG419 switches and like them. For input selection I use them between an input resistor and the inverting input of an inverting amplifier circuit. Works well. The only thing I've noticed in this configuration is a bit of sensitivity to power supply quality. Perhaps this is less of an issue when using it in a configuration where higher voltages are switched.

Best,

Rutger
