Clock Input Pin for Channel B.
Enable Duty Cycle Stabilizer (DCS) Mode.
Data Output Format Select Pin (Low for Offset Binary, High for Twos Complement).
Power-Down Function Selection for Channel B.
Logic 0 enables Channel B. Logic 1 powers down Channel B (outputs static, not High-Z).
Output Enable Pin for Channel B.
Logic 0 enables Data Bus B. Logic 1 sets outputs to High-Z.
Channel B Data Output Bits.
Digital Output Ground.
Digital Output Driver Supply. Must be decoupled to DRGND with a minimum 0.1 μF capacitor.
Recommended decoupling is 0.1 μF capacitor in parallel with 10 μF capacitor.
Out-of-Range Indicator for Channel B.
Channel A Data Output Bits.
Out-of-Range Indicator for Channel A.
Output Enable Pin for Channel A.
Logic 0 enables Data Bus A. Logic 1 sets outputs to High-Z.
Power-Down Function Selection for Channel A.
Logic 0 enables Channel A. Logic 1 powers down Channel A (outputs static, not High-Z).
Data Multiplexed Mode.
(See Data Format section for how to enable; high setting disables output data multiplexed mode.)
Shared Reference Control Pin (Low for Independent Reference Mode, High for Shared Reference Mode).
Clock Input Pin for Channel A.
For the 64-Lead LFCSP only, there is an exposed pad that must connect to AGND.
