PIN 1

INDICATOR

NOTES

1. DNC = DO NOT CONNECT. DO NOT CONNECT TO THIS PIN.

2. THE EXPOSED PADDLE MUST BE SOLDERED TO THE PCB ANALOG

GROUND TO ENSURE PROPER FUNCTIONALITY AND HEAT

DISSIPATION, NOISE, AND MECHANICAL STRENGTH BENEFITS.

Description

ADC Power Pins

1, 2, 35, 36, 37, 40, 42,

44, 45, 48

AVDD

Supply

Analog Power Supply (1.8 V Nominal).

8, 27

DRVDD

Supply

Digital Output Driver Supply (1.8 V Nominal).

7, 28

DRGND

Ground

Digital Output Ground.

0

AGND

Ground

Analog Ground. Pin 0 is the exposed thermal pad on the bottom of the

package. This is the only ground connection, and it must be soldered to

the PCB analog ground to ensure proper functionality and heat dissipation,

noise, and mechanical strength benefits.
