ANALOG DEVICES  AD8436ACPZ-R7  RMS to DC Converter, Low Power, 1 MHz, -40 °C, 125 °C, LFCSP, 20 Pins

Product Overview

The AD8436ACPZ-R7 is a new generation translinear precision true RMS-to-DC Converter loaded with options. It computes a precise DC equivalent of the RMS value of 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 ensured accuracy of ≤±0.5% and ≤10μV output offset result from the latest Analogue Devices, Inc., technology. The crest factor error is <0.5% for CF values between 1 and 10. The AD8436 delivers true RMS results at 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.
