10.12 Analog output
The DAC1205D650 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 using
a load resistor R
L
to the 3.3 V analog power supply (V
DDA(3V3)
).
Refer to
Figure 12 “Equivalent analog output circuit (one DAC)”
for the equivalent analog
output circuit of one DAC. This circuit consists of a parallel combination of NMOS current
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
o(p-p)
depending on the application, the
following stages and the targeted performances.
