Table 38.
Default settings are shown highlighted.
The DAC1405D650 has two output channels each of which produces two complementary
current outputs. These allow the even-order harmonics and noise to be reduced. The pins
are IOUTAP/IOUTAN and IOUTBP/IOUTBN respectively and need to be connected via a
load resistor R
For the equivalent analog output circuit of one DAC, refer to
output circuit (one
sources, and their associated switches, for each segment.
The cascode source configuration increases the output impedance of the source, thus
improving the dynamic performance of the DAC by introducing less distortion.
The device can provide an output level of up to 2 V
stages and the targeted performances
