8.1.6 Reference Voltage Rejection Ratio

The voltage applied to the VREF pin sets the zero current output voltage for the TMCS1100. Ideally, the zero current output voltage directly tracks VREF. Light internal mismatch can cause minor errors, however. When the reference voltage deviates from half of the supply, an additional effective output offset error is introduced into the device transfer function. The reference voltage rejection ratio (RVRR) is the effective change in output offset voltage due to this deviation. Error due to reference rejection can be calculated by Equation 10.
