Optional Output Configuration

Certain functional applications require a series output

resistor yet also demand that the comparator be

connected directly to the DUT, not via the backmatch

resistor. To create this configuration, two distinct

termination resistors may be connected to the VHIGH

and VLOW input pins (see Figure 13).
