PRODUCTION DATA.
Dynamic currents are present at the REFP and REFM pins during the conversion phase, and excellent decoupling is required to achieve optimum performance. Place a 22-µF, X7R-grade, ceramic capacitor with at least a 10-V rating between the REFP and the REFM pins, as illustrated in Figure 108. Select 0603- or 0805-size capacitors to keep the equivalent series inductance (ESL) low. Connect the REFM pin to the decoupling capacitor before connecting to a ground via.
