Digital data output pins that make up the 14-bit conversion result.
D0 (pin 13) is the LSB, while D13 (pin 29) is the MSB of the output
word. Output levels are CMOS compatible.
Data Ready Strobe. The data output transition is synchronized with
the falling edge of this signal. This signal switches at the same
frequency as the CLK input.
Positive analog supply pins. These pins should be connected to a
quiet voltage source and be bypassed to AGND with 0.1 µF
capacitors located close to the power pins.
The ground return for the analog supply.
The exposed pad on back of package must be soldered to ground
plane to ensure rated performance.
Positive driver supply pin for the output drivers. This pin should be
connected to a quiet voltage source and be bypassed to DRGND
with a 0.1 µF capacitor located close to the power pin.
The ground return for the digital output driver supply. This pins
should be connected to the system digital ground, but not be
connected in close proximity to the ADC's AGND pins.
