Paddle

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.

ADC Analog

VIN+A

Input

Differential Analog Input Pin (+) for Channel A.

VIN−A

Input

Differential Analog Input Pin (−) for Channel A.

VIN+B

Input

Differential Analog Input Pin (+) for Channel B.

VIN−B

Input

Differential Analog Input Pin (−) for Channel B.

VCM

Output

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

decoupled to ground using a 0.1 μF capacitor.

CLK+

Input

ADC Clock Input—True.

CLK−

Input

ADC Clock Input—Complement.

Digital Input

SYNC

Input

Digital Synchronization Pin. Slave mode only.

Digital Outputs

ORB+

Output

Channel B LVDS Overrange Output—True. The overrange indication is

valid on the rising edge of the DCO.

ORB−

Output

Channel B LVDS Overrange Output—Complement. The overrange

indication is valid on the rising edge of the DCO.
