[Example 1] Digital output value when the analog input value varied from 0 to 1V
When the high resolution mode and the input range of 0 to 10V is
specified for the Q68AD-G
The variation of the digital output value at the time constant setting of
1000ms (1s) is as shown below.
1000ms (1s) after the analog input value has reached 1V, the digital
output value reaches 63.2% of the value attained when the sampling
processing is selected.
[Example 2] Digital output value when the variation of the analog input value has a
ringing waveform
When the high resolution mode and the input range of 0 to 10V is
specified for the Q68AD-G
The variations of the digital output values at the time constant setting
of 2000ms (2s), at the time constant setting of 1000ms (1s), and at
the moving average processing of 16 times are as shown below.
