I have two questions for ADuCM320 VDAC below.
According to the UG-498 page 42, it stated equivalent circuit. (Please see the attached file)
Q1) If reverse current is injected to the output side of the DAC_BUF, Is there any problems that we need to estimate?
Q2) Since there is a description of the "500 μA maximum", Is it acceptable for reverse current 500 μA maximum as well?
