9 Power Supply Recommendations

In a typical frequency-inverter application, the high-side power supply (AVDD) for the AMC1336 is generated from the controller-side supply (DVDD) of the device by an isolated dc/dc converter circuit. Figure 53 shows a low-cost solution based on the push-pull driver SN6501 and a transformer that supports the desired isolation voltage ratings. TI recommends using a low-ESR decoupling capacitor of 0.1 µF and an additional capacitor of minimum 1 µF for both supplies of the AMC1336. Place these decoupling capacitors as close as possible to the device power-supply pins to minimize supply current loops and electromagnetic emissions.

The AMC1336 does not require any specific power up sequencing. Consider the analog settling time tASTART as specified in the Table 10 table after ramp up of the AVDD high-side supply.

Connect the high-side ground pin AGND of the AMC1336 to one of the analog inputs AINx to avoid common-mode input voltage range violations.
