FUNCTION
DESCRIPTION
1 – 6
CH0 – CH5
Analog Inputs
The analog inputs must be free of noise with respect to AGND.
7
COM
Common
The common pin defines the zero reference point for all single ended inputs. It must be free of noise and is
usually tied to the analog ground plane.
8
DGND
Digital Ground
This is the ground for the internal logic. Tie to the ground plane.
9V
–
Negative Supply
Tie V
– to most negative potential in the circuit (Ground in single supply applications).
10
AGND
Analog Ground
AGND should be tied directly to the analog ground plane.
11
VREF
Ref. Input
The reference inputs must be kept free of noise with respect to AGND.
12
DIN
Data Input
The A/D configuration word is shifted into this input.
13
DOUT
Digital Data Output The A/D conversion result is shifted out of this output.
14
CS
Chip Select Input
A logic low on this input enables data transfer.
15
CLK
Clock
This clock synchronizes the serial data transfer and controls A/D conversion rate.
16
VCC
Positive supply
This supply must be kept free of noise and ripple by bypassing directly to the analog ground plane.

13, 14 REF
–, REF+ Ref. Inputs
The reference inputs must be kept free of noise with respect to AGND. The A/D sees a reference voltage equal
to the difference between REF
+ and REF–.
15
DIN
Data Input
The A/D configuration word is shifted into this input.
16
DOUT
Digital Data Output The A/D conversion result is shifted out of this output.
17
CS
Chip Select Input
A logic low on this input enables data transfer.
18
CLK
Clock
This clock synchronizes the serial data transfer and controls A/D converion rate.
19, 20 AVCC, DVCC
Positive Supplies
These supplies must be kept free of noise and ripple by bypassing directly to the analog ground plane. AVCC
and DVCC must be tied together.
