Power Sequencing
The voltage applied to REF should not exceed V
DD
at
any time. If proper power sequencing is not possible,
connect an external Schottky diode between REF and
V
DD
to ensure compliance with the absolute maximum
ratings. Do not apply signals to the digital inputs before
the device is fully powered-up.
Power-Supply Bypassing and
Ground Management
Bypass V
DD
with a 0.1μF capacitor, located as close to
V
DD
and GND as possible. Careful PC board layout
minimizes crosstalk among DAC outputs and digital
inputs. Figure 10 shows suggested circuit board layout
to minimize crosstalk.
Unipolar-Output, Two-Quadrant
Multiplication
In unipolar operation, the output voltages and the refer-
ence input are the same polarity. Figure 11 shows the
MAX5258/MAX5259 unipolar configuration, and Table 2
shows the unipolar code.
