NAME

FUNCTION

1, 2, 3, 6, 9, 12, 14–17,

20, 23, 26, 27, 30, 52–56, EP

GND

Converter Ground. Analog, digital, and output driver grounds are internally

connected to the same potential. Connect the converter’s EP to GND.

4

CLKP

Differential Clock, Positive Input Terminal

5

CLKN

Differential Clock, Negative Input Terminal

7, 8, 18, 19, 21, 22, 24, 25, 28

Analog Supply Voltage. Provide local bypassing to ground with 0.1µF to 0.22µF

capacitors.

10

INP

Differential Analog Input, Positive Terminal

11

INN

Differential Analog Input, Negative/Complementary Terminal

13

CM

Common-Mode Reference Terminal

29

Digital Supply Voltage. Provide local bypassing to ground with 0.1µF to 0.22µF

capacitors.

31, 41, 42, 51

Digital Output Driver Supply Voltage. Provide local bypassing to ground with

0.1µF to 0.22µF capacitors.

32

DOR

Data Overrange Bit. This control line flags an overrange condition in the ADC.

If DOR transitions high, an overrange condition was detected. If DOR remains low,

the ADC operates within the allowable full-scale range.

DAV

Data Valid Output. This output can be used as a clock control line to drive an

external buffer or data-acquisition system. The typical delay time between the

falling edge of the converter clock and the rising edge of DAV is 6.5ns.
