• Manufacturer Part Number: max5230beeet
• Description: 3v/5v, 12-bit, Serial Voltage-output Dual Dacs With Internal Reference
• Manufacturer: Maxim Integrated Products, Inc.

On power-up, the input and DAC registers are cleared
to either zero (RSTV = DGND) or midscale (RSTV =
V
with a 0.1µF capacitor to AGND, and bypass V
a 0.1µF capacitor to DGND. Minimize lead lengths to
reduce lead inductance.
Digital and AC transient signals on AGND or DGND can
create noise at the output. Connect AGND and DGND
to the highest quality ground available. Use proper

grounding techniques, such as a multilayer board with a
low-inductance ground plane or star connect all ground
return paths back to the MAX5230/MAX5231 AGND.
Carefully lay out the traces between channels to reduce
AC cross-coupling and crosstalk. Wire-wrapped boards
and sockets are not recommended. If noise becomes
an issue, shielding may be required.
