Notes

11.

Section “MODES OF OPERATION”, page 16 has a detailed description of the different operating modes of the 34716

12.

Design information only, this parameter is not production tested.

13.

Overall output accuracy is directly affected by the accuracy of the external feedback network, 1% feedback resistors are recommended.

14.

±1% is assured at room temperature.
