The AD8436 is a new generation, translinear precision, low power, true rms to dc converter that is loaded with options. It computes a precise dc equivalent of the rms value ac waveforms, including complex patterns such as those generated by switch mode power supplies and triacs. Its accuracy spans a wide range of input levels and temperatures. The AD8436 delivers instant true rms results for less cost than misleading peak, averaging, or digital solutions. On-board buffer amplifiers enable the widest range of options for any rms to dc converter available, regardless of cost. For minimal applications, only a single external averaging capacitor is required. The built in high impedance FET buffer provides an interface for external attenuators, frequency compensation, or driving low impedance loads.
