Integrated Circuit True RMS-to-DC Converter

The AD536A is a complete monolithic integrated circuit that performs true rms-to-dc conversion. It offers performance comparable or superior to that of hybrid or modular units costing much more. The AD536A directly computes the true rms value of any complex input waveform containing ac and dc components. A crest factor compensation scheme allows measurements with 1% error at crest factors up to 7. The wide bandwidth of the device extends the measurement capability to 300 kHz with less than 3 dB errors, for signal levels greater that 100 mV.
An important feature of the AD536A not previously available in rms converters, is an auxiliary dB output pin. The logarithm of the rms output signal is brought out to a separate pin to allow the dB conversion, with a useful dynamic range of 60 dB. Using an externally supplied reference current, the 0 dB level CAN be conveniently set to correspond to any input level from 0.1 V to 2 V rms.
The AD536A is laser trimmed to minimize input and output offset voltage, to optimize positive and negative waveform symmetry (dc reversal error), and for full-scale accuracy at 7 V rms. As a result, no external trims are required to achieve the rated unit accuracy.
The input and output pins are fully protected. The input circuitry CAN take overload voltages well beyond the supply levels. Loss of supply voltage with the input connected to external circuitry does not cause the device to fail. The output is short-circuit protected.
The AD536A is available in two accuracy grades (J and K) for commercial temperature range (0C to +70C) applications, and one grade (S) rated for the -55C to +125C extended range. The AD536AK offers a maximum total error of 2 mV 0.2% of reading, while the AD536AJ and AD536AS have maximum errors of 5 mV 0.5% of reading. All three versions are available in a hermetically sealed 14-lead DIP or 10-lead TO-100 metal CAN The AD536AS is also available in a 20-terminal leadless hermetically sealed ceramic chip Carrier
