7.2.2.2 Detailed Design Procedure

Set RBIAS such that the current through the shunt reference, IREF, is greater than IREFMIN + ILOAD.

Use a resistor divider to set the required voltage to the input of the amplifier. The TLV2401 requires an input bias current maximum of 350pA which allows the use of larger resistor values to save power.
