Settling time is an important specification for applications requiring faster and more accurate results. It is typically specified for 0.1% and 0.01% accuracies and is provided in the datasheets. Additionally, it varies with the value of the RMS averaging capacitor required by the application. Faster settling time RMS-to-DC converters enable new features and system designs. As can be seen, the AD8436 settles quickly and to the same value over the entire operating range. Because of this feature, a multiplexed RMS-to-DC system can be implemented for 3-phase power metering; this is simpler and lowers system design cost compared with traditional solutions. Additionally, For digital multi-meters using fast settling RMS-to-DC converters, more readings per second can be achieved.
