Analog Outputs (IOUTP, IOUTN)
The MAX5887 outputs two complementary currents
(IOUTP, IOUTN) that can be operated in a single-
ended or differential configuration. A load resistor can
convert these two output currents into complementary
single-ended output voltages. The differential voltage
existing between IOUTP and IOUTN can also be con-
verted to a single-ended voltage using a transformer or
a differential amplifier configuration. If no transformer is
used, the output should have a 50
termination to the
analog ground and a 50
resistor between the outputs.
Although not recommended for single-ended operation,
because of additional noise pickup from the ground
