Notes

11.

See section “MODES OF OPERATION”, page 14 has a detailed description of the different operating modes of the 34712

12.

Design information only, this parameter is not production tested.

13.

±1% is assured at room temperature.

14.

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

15.

The 1% output voltage regulation is only guaranteed for a common mode voltage range greater than or equal to 0.7V at room

temperature.
