operating from a 3V supply versus 5V for the MA515 and
MAX539. The DOUT port also has 4mA driving capability
for greater fan-out when daisy-chaning to other digital
inputs.
Monotonicity
The XRD54L08/L10/L12 family of DACs are monotonic
over the entire temperature range.
Micro-Power Operation
The XRD54L08/L10/L12 are the lowest power DACs 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
XRD54L08/L10/L12 family of DACs from an analog +3V
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 (V
capacitors are recommended for low impedance, wide
band power supply bypass. If only one +3V power supply
is available for both analog and digital circuity isolate the
analog power supply to the XRD54L08/L10/L12 DAC with
an inductor or ferrite bead before the local bypass
capacitors.
