DAC8820: the driving current of output of the the DAC8820EVM evaluation module

user5244450

Part Number: DAC8820
Other Parts Discussed in Thread: OPA2277,

I would like to use the output of the DAC8820EVM evaluation module to connect the appropriate load, so I would like to consult the drive current of output of evaluation module, I did not find the corresponding information in the evaluation board documentation, can you tell me where  I can find the corresponding information, how much is it driving current?

    Hello,

    Welcome to E2E and thank you for your query. The DAC8820 is an unbuffered MDAC and hence, we need to use an amplifier at the output stage. The EVM uses OPA2277 for this purpose. So, you can consult the datasheet of OPA2277 for the output drive strength specs.

    Hope that answers your question.
