Setup
Unless other test conditions are specified.
In the following graphs, the input signal is seldom full scale.
C
below 20 kHz. The value of the capacitor is divided by two when the input frequency is
multiplied by 2.
f
is a filter capacitor to cut the HF noise. Its value is 10 nF for input frequencies equal to or
AVCC = DVCC = VCCBI = VCCBE = 2.5 V
VREFP = 1 V
VREFM = 0 V
INCM = Vin/2
REFMODE = 1 (internal references are disabled)
Vin = 1 Vpp
Tamb = 25 °C
A square clock is applied
