FIGURE 3. Simple, Low Component Count, Self -Bias Reference application. Because of resistor tolerances, the reference
voltages can vary by as much as 6%. Choose an amplifier that can drive a dynamic capacitance (see text).

FIGURE 4. Better defining the ADC Reference Voltage. Self-bias is still used, but the reference voltages are trimmed by
providing a small trim current with the operational amplifiers.
