7.4 Power Supply Recommendations

The AMC0106M05 does not require any specific power-up sequencing. The high-side power supply (AVDD) is decoupled with a low-ESR, 100nF capacitor (C1) parallel to a low-ESR, 1μF capacitor (C2). The low-side power supply (DVDD) is equally decoupled with a low-ESR, 100nF capacitor (C3) parallel to a low-ESR, 1μF capacitor (C4). Place all four capacitors (C1, C2, C3, and C4) as close to the device as possible. Figure 7-3 shows a decoupling diagram for the AMC0106M05.

Capacitors have to provide adequate effective capacitance under the applicable DC bias conditions that are experienced in the application. Multilayer ceramic capacitors (MLCC) typically exhibit only a fraction of the nominal capacitance under real-world conditions. Take this factor into consideration when selecting these capacitors. This problem is especially acute in low-profile capacitors, in which the dielectric field strength is higher than in taller components. Reputable capacitor manufacturers provide capacitance versus DC bias curves that greatly simplify component selection.
