less than 100nA of continuous wiper current.
Note 4:
Measured with 20pF load capacitor.
Note 5:
Absolute tolerance is defined as the variation of the attenuation for any given tap from its expected value.
Note 6:
Tap-to-tap tolerance is defined as the variation between any two adjacent taps from the typical value of 1dB.
Note 7:
Supply current when f
