Functional Description
(Continued)
Optional — The UP die pad is bounded on each side by a
logic High and a logic Low pad. This allows the state of UP
to be chosen on the TCP to eliminate an input pin.

OLTAGE SUPPLY
Optional positive supply voltage that provides a constant
bias current to the output amplifiers to extend dynamic
range. When separately provided, V
