ended output voltages. The differential voltage existing
between IOUTP and IOUTN can also be converted to a
single-ended voltage using a transformer or a differen-
tial amplifier configuration. If no transformer is used, the
output should have a 50Ω termination to the analog
ground and a 50Ω resistor between the outputs.

Although not recommended because of additional
noise pickup from the ground plane, for single-ended
operation IOUTP should be selected as the output, with
IOUTN connected to AGND. Note that a single-ended
output configuration has a higher 2nd-order harmonic
distortion at high output frequencies than a differential
output configuration.
