(Note 1)
(V
Note 1: All devices are 100% production tested at T
Note 2: Bandwidth is measured from H to W at the -6dB wiper tap position (see Typical Operating Characteristics).
Note 3: These specifications are only valid for I
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
Note 8: Supply current when wiper position is not changing.
