9.2.2.1 Resistor Divider Selection

Use Equation 1 through Equation 4 to calculate the resistor divider values and target threshold voltages.

Equation 1. RT = R1 + R2 + R3

Select a value for RT such that the current through the divider is approximately 100 times higher than the input current at the INA+ and INB– terminals. The resistors can have high values to minimize current consumption as a result of low-input bias current without adding significant error to the resistive divider. See the application note Optimizing Resistor Dividers at a Comparator Input (SLVA450) for details on sizing input resistors.

Use Equation 2 to calculate the value of R3.

where

    Use Equation 3 or Equation 4 to calculate the value of R2.

    where

      Equation 4. TLV6700 q_r2b_slvsci7.gif

      where

        The worst-case tolerance can be calculated by referring to Equation 13 in application report SLVA450, Optimizing Resistor Dividers at a Comparator Input (available for download at www.ti.com). An example of the rising threshold error, VMON(OV), is given in Equation 5.
