port also has 4mA driving capability for greater fan-out
when daisy-chaning to other digital inputs.
Monotonicity
The XRD5408/10/12 family of DACs are monotonic over
the entire temperature range.
Micro-Power Operation
The XRD5408 is the lowest power in their class. The
quiescent current rating does not include the reference
ladder current. Power can be saved when the part is not in
use by setting the DAC code to all “0”s assuming the
output load is referenced to ground. This minimizes the
DAC output load current. An analog switch placed in
series with the reference ladder can toggle the reference
voltage off when the circuit is inactive to minimize power
consumption.
Power Supply and Grounding
Best parametric results are obtained by powering the
XRD5408/10/12 family of DACs from an analog +5V
power supply and analog ground. Digital power supplies
and grounds should be separated or connected to the
analog supplies and grounds only at the low-impedance
power-supply source. This is best accomplished on a
multilayer PCB with dedicated planes to ground and
power. The DACs should be locally bypassed with both
0.1 F and 2.2 F capacitors mounted as close as possible
to the power supply pin (VDD). Surface mount ceramic
capacitors are recommended for low impedance, wide
band power supply bypass. If only one +5V power supply
is available for both analog and digital circuity isolate the
analog power supply to the XRD5408/10/12 DAC with an
inductor or ferrite bead before the local bypass
capacitors.
