Hi All.

I have a question about AD7699 Internal REF.

In D/S, " Turn-On Settling Time   5ms typ  @CREF = 10 μF"
However, the customer's evaluation result was slower than the spec.

 

Test conditions

*CREF = 10uF, No Load.

*Configuration resister[5:3] = 001 (Internal reference and temperature sensor enabled. REF = 4.096 V buffered output)

please check the attached file.

 

Does ADI have a similar measurement data?

The customer needs a reason why the result will not be D / S .

 

Best regards,

Hiroshi
