Common-mode voltage. The input signal can be centered on a dc common-mode voltage in the range specified in Figure 28 and Figure 29.
See the Terminology section.
Analog inputs with slew rates exceeding 27 V/μs (full-scale input sine wave > 3.5 MHz) within the acquisition time can cause the converter to return an
incorrect result.
Because the input spans of V
The AD7450A is functional with a reference input from 100 mV and for V
The AD7450A is functional with a reference input from 100 mV and for V
Guaranteed by characterization.
Measured with a midscale dc input.
