PRODUCTION DATA
The VCC power terminal for the device requires the direct placement of low-ESR noise-decoupling capacitance from the VCC terminal to the GND terminal. Ceramic capacitors with stable dielectric characteristics over temperature are recommended, such as X7R or better. Depending on the operating temperature range of the application, X5R may be acceptable, but the drop in capacitance value at high temperature and with applied DC-bias may not be tolerable. Avoid dielectrics with poor temperature stability.
The recommended decoupling capacitor is a 1-µF 0805-sized 50-V X7R capacitor, ideally with (but not essential) a second, smaller, parallel 100-nF 0603-sized 50-V X7R capacitor. Higher voltage-rated parts can also be used. The use of 25-V rated parts is not recommended, due to reduction in effective capacitance value with applied DC bias.
