So far you've spoken only about power applications. What other types of applications would the AD8436 fulfill?

Any type of application using symmetrical 2 or 4-diode bridges. Examples of this would be low-frequency amplitude de-modulation, where the carrier frequency is relatively low (e.g., 50kHz). The AD8436 also features low errors with high crest-factor waveforms such as current spikes during the transition of switch-mode power supplies.
