NOTES

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

2. THE EXPOSED THERMAL PADDLE ON THE BOTTOM OF THE PACKAGE

PROVIDES THE ANALOG GROUND FOR THE PART. THIS EXPOSED

PADDLE MUST BE CONNECTED TO GROUND FOR PROPER OPERATION.

Description

Digital Output Driver Supply (1.8 V Nominal).

Analog Power Supply (1.8 V Nominal).

Analog Ground. The exposed thermal paddle on the bottom of the

package provides the analog ground for the part. This exposed paddle

must be connected to ground for proper operation.

Do No Connect. Do not connect to this pin.

Differential Analog Input Pin (+).

Differential Analog Input Pin (−).

Common-Mode Level Bias Output for Analog Inputs. This pin should be

decoupled to ground using a 0.1 μF capacitor.

ADC Clock Input—True.
