8 / 12 page _____________Analog Considerations Reference and Input The VREF+ and VREF- inputs of the converter define the zero and the full-scale of the ADC. In other words, the voltage at VREF- is equal to the input voltage that pro- duces an output code of all zeros, and the voltage at VREF+ is equal to input voltage that produces an output code of all ones (Figure 7). Figure 8 shows some possible reference configura- tions. For the MAX154/MAX158, a 0.01µF bypass capacitor to GND should be used to reduce the high- frequency output impedance of the internal reference. Larger capacitors should not be used, as this degrades the stability of the reference buffer. The 2.5V reference output is with respect to the GND pin. Bypassing A 47µF electrolytic and 0.1µF ceramic capacitor should be used to bypass the VDD pin to GND. These capaci- tors must have minimum lead length, since excess lead length may contribute to conversion errors and instability. If the reference inputs are driven by long lines, they should be bypassed to GND with 0.1µF capacitors at the reference input pins.
