I purchased a DAC8760EMC-EVM from Mouser.com (serial number 001 on the silk screen). When +12V is applied to the +15V power connector with the -15V and GND connected to ground, the tantalum capacitors on the power pins get hot and the current draw is 2 amps. The resistance between +12V and ground is 6 ohms in either direction. I know I did not misapply power, as I was very careful about that. Is the board defective or what should I do differently?
Below is the email I received from Mouser.
Hi Richard,
This is a follow up on your return request.
For all defective development tools, you must first contact TI_s E2E forum for tech support at http://e2e.ti.com/.
If the TI tech determines the part is defective, please return the kit to Mouser along with TI's reference number and/or forum thread with TI tech.
We will then send you a replacement once this process has been completed and it has been confirmed the part is defective.
Please let us know if you have further questions.
We appreciate your business.
Respectfully,
Lylliana Williams
