I would like to use digital potentiometers for digital tuning of an =
analog filter, as an alternative to a noisy Switched Capacitor filter, =
or more expensive and complex DSP solution. The problem with most =
Digital Pots, is that the end to end resistance tolerance is 20% of =
greater. I am searching for a digital potentiometer with precision =
resistance settings <1%. So a setting of 12.4K would be 12.4K +/-1%. I =
would appreciate any leads. Thanks!
