8.2.2.5 Selecting VDD Capacitor

Bypass capacitors for VDD is essential for achieving reliable performance. TI recommends choosing low-ESR and low-ESL, surface-mount, multi-layer ceramic capacitors (MLCC) with sufficient voltage ratings, temperature coefficients, and capacitance tolerances. A 50-V, 10-μF MLCC and a 50-V, 0.22-μF MLCC are selected for the CVDD capacitor. If the bias power supply output is located a relatively long distance from the VCC pin, a tantalum or electrolytic capacitor with a value greater than 10 μF should be used in parallel with CVDD.

Note:

DC bias on some MLCCs will impact the actual capacitance value. For example, a 25-V, 1-μF X7R capacitor is measured to be only 500 nF when a DC bias of 15-VDC is applied.
