Analog input common. Connect to a quiet point in
analog ground near the driving device. See section
1.2.
Positive analog supply pin. Connect to a clean,
quiet voltage source of +5V. V

should have
a common supply and be separately bypassed with
a 5μF to 10μF capacitor and a 0.1μF chip capacitor.
The ground return for the analog supply. AGND and
DGND should be connected together close to the
ADC12191 package. See section 5.0.

The digital output driver supply pin. This pin can be
operated from a supply voltage of 3V to 5V, but the
voltage on this pin should never exceed the V
D
supply pin voltage.
The ground return for the output drivers. This pin
should be returned to a point in the digital ground
that is removed from the other ground pins of the
ADC12191.
