Unipolar Configuration
Figure 2 shows a typical unipolar DAC application for
the LTC2641. Tables 1a, 1b and 1c show the unipolar
binary code tables for 16-bit, 14-bit and 12-bit operation.

The external amplifier provides a unity-gain buffer. The
LTC2642 can also be used in unipolar configuration by
tying RFB and INV to REF. This provides power-up and
clear to midscale.
