Power Sequencing
The voltage applied to REF should not exceed VDD at
any time. If proper power sequencing is not possible,
connect an external Schottky diode between REF and
VDD 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 VDD with a 0.1F capacitor, located as close to
VDD 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.
