MAX5232/MAX5233
Power-Supply and Bypassing
Considerations
On power-up, the input and DAC registers are cleared
to either zero (RSTV = DGND) or midscale (RSTV =
VDD). Bypass VDD with a 4.7F capacitor in parallel
with a 0.1F capacitor to AGND, and bypass VDD with
a 0.1F capacitor to DGND. Minimize lead lengths to
reduce lead inductance.
Grounding and Layout Considerations
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 MAX5232/MAX5233 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.
