• Manufacturer Part Number: max5133beee
• Description: 5v/3v, 13-bit, Serial, Force/sense Dacs With 10ppm/ ? Internal Reference
• Manufacturer: Maxim Integrated Products, Inc.

The MAX5132/MAX5133 have multiplying capabilities
within the reference input voltage range specifications.
Figure 13 shows a technique for applying a sinusoidal
input to REF, where the AC signal is offset before being
applied to the reference input.
On power-up, the input and DAC registers are cleared
to either zero (RSTVAL = DGND) or midscale (RSTVAL
= V

capacitor in parallel with a 0.1µF capacitor to AGND.
Minimize lead lengths to reduce lead inductance.
Digital and AC signals coupling to AGND can create
noise at the output. Connect AGND to the highest quali-
ty ground available. Use proper grounding techniques,
such as a multilayer board with a low-inductance
ground plane. Wire-wrapped boards and sockets are
not recommended. If noise becomes an issue, shield-
ing may be required.
