I/O

DESCRIPTION

AGND

1, 19

Analog ground

AIN

27

I

Analog input

AVDD

28

5-V analog supply

CLK

15

I

Clock input

CML

26

O

Bypass for an internal bias point. Typically a 0.1

µF capacitor minimum is connected from this terminal to ground.

DGND

14, 20

Digital ground

DVDD

18

5-V digital supply

DRVDD

2

3.3-V/5-V digital supply. Supply for digital input and output buffers.

DRGND

13

3.3-V/5-V digital ground. Ground for digital input and output buffers.

D0 –D9

3–12

O

Digital data out. D0:LSB, D9:MSB

OE

16

I

Output enable. When OE = low or NC, the device is in normal operating mode. When OE = high, D0–D9 are high

impedance.

REFBF

24

I

Reference bottom force

REFBS

25

I

Reference bottom sense

REFTF

22

I

Reference top force

REFTS

21

I

Reference top sense

STBY

17

I

Standby enable. When STBY = low or NC, the device is in normal operating mode. When STBY = high, the device

is in standby mode.
