8.4 Power Supply Recommendations

The AMC1301 does not require any specific power-up sequencing. The high-side power supply (AVDD) is decoupled with a low-ESR, 100-nF capacitor (C1) parallel to a low-ESR, 1-µF capacitor (C2). The low-side power supply (DVDD) is equally decoupled with a low-ESR, 100-nF capacitor (C3) parallel to a low-ESR, 1-µF capacitor (C4). Place all four capacitors (C1, C2, C3, and C4) as close to the device as possible.

The ground reference for the high-side (AGND) is derived from the end of the shunt resistor that is connected to the negative input (INN) of the device. For best DC accuracy, use a separate trace to make this connection instead of shorting AGND to INN directly at the device input. If a four-terminal shunt is used, the device inputs are connected to the inner leads and AGND is connected to the outer lead on the INN side of the shunt. Figure 8-5 shows a decoupling diagram of the AMC1301.
