MAX5888

3.3V, 16-Bit, 500Msps High Dynamic

Performance DAC with Differential LVDS Inputs

_______________________________________________________________________________________

Analog Outputs (IOUTP, IOUTN)

The MAX5888 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

Ω termination to the

analog ground and a 50

Ω resistor between the outputs.

Although not recommended, because of additional
noise pickup from the ground plane, for single-ended
