Part Number: DAC81416EVM
Hello Team,
In one of my customer experiments, they are using a DAC81416EVM. Unfortunately, the first one stopped working after they switched from 20V to 40V (maximum operational voltage range described in the datasheet) and while searching for an error, the second one was destroyed too after switching to 40V (the Vcc bonding wire burned through the casing).
After detailed reviewing the schematics they spotted a possible design mistake. The capacitors C14 and C15 (directly positioned at the Vcc pins) are designed for 16V. When using 40V (maximum operational voltage range described in the datasheet) for Vcc the capacitors (possibly) cause a short circuit and destroy the DAC again.
They are wondering if they can ask for a replacement board and a redesigned board? Is there a possibility to get two boards with the old design so that we can finish the 20V experiments.
Regards,
Renan
