I have a question AD7124 Digital Output P1-P4.
Digital Output P1-P4, How many max current which can be driven directly some?
How many max current DOUT ?
Digital outputs/logic outputs in general are specified to guarantee particular voltage high and low levels for a given source/sink current. For AD7124, the outputs can source 100uA and still be guaranteed to output a minimum valid logic high output level AVDD-0.6V (P1 to P4) and IOVDD - 0.35V (DOUT) and can sink 100uA to guarantee a maximum valid logic low output level 0.4V (P1-P4 and DOUT). May I know what is your application and why do you need a maximum current rating? If your application require the outputs to sink and source more current than this specified current, the output levels cannot be guaranteed and the outputs should be buffered.
Thnak you for your answer!
