It offers performance which is comparable or superior to that of hybrid or modular units costing much more. The ADA directly computes the true rms value of any complex input waveform containing ac and dc components. The wide bandwidth of the device extends the measurement capability to kHz with 3 dB error for signal levels above mV. An important feature of the ADA not previously available in rms converters is an auxiliary dB output. 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 by the user to correspond to any input level from to 2 volts rms. The ADA is laser trimmed at the wafer level for input and output offset, positive and negative waveform symmetry dc reversal error , and full-scale accuracy 7 V rms. As a result, no external trims are required to achieve the rated unit accuracy.

There is full protection for both inputs and outputs. The input circuitry can take overload voltages well beyond the supply levels. Loss of supply voltage with inputs connected will not cause unit failure. The output is short-circuit protected. The ADAK offers a maximum total error 0. All three versions are available in either a hermetically sealed lead DIP pin TO metal can. The ADAS is also available a leadless hermetically sealed ceramic chip carrier.

The ADA computes the true root-mean-square level of a complex ac or ac plus dc input signal and gives an equivalent dc output level. The true rms value of a waveform is a more useful quantity than the average rectified value since it relates directly to the power of the signal.

The rms value of a statistical signal also relates to its standard deviation. The crest factor of a waveform is the ratio of the peak signal swing to the rms value.

The crest factor compensation scheme of the ADA allows measurement of highly complex signals with wide dynamic range. The only external component required to perform measurements to the fully specified accuracy is the capacitor which sets the averaging period.

The value of this capacitor determines the low frequency ac accuracy, ripple level and settling time. The ADA will operate equally well from split supplies or a single supply with total supply levels from to 36 volts. The one milliampere quiescent supply current makes the device well-suited for a wide variety of remote controllers and battery powered instruments.

The ADA directly replaces the AD and provides improved bandwidth and temperature drift specifications. One Technology Way, P. Box , Norwood, MA , U. Temperature vs. Specifications subject to change without notice. Specifications shown in boldface are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min and max specifications are guaranteed, although only those shown in boldface are tested on all production units.

Supply Voltage Dual Supply. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. The ADA is simple to connect for the majority of high accuracy rms measurements, requiring only an external capacitor to set the averaging time constant.

The standard connection is shown in Figure 1. In this configuration, the ADA will measure the rms of the ac and dc level present at the input, but will show an error for low frequency inputs as a function of the filter capacitor, CAV, as shown in Figure 5. The accuracy at higher frequencies will be according to specification. If the ADA is driven with power supplies with a considerable amount of high frequency ripple, it is advisable to bypass both supplies to ground with 0.

LFNP : 1. The EV kits operate over a wide input-voltage range and uses primary-side feedback to regulate output voltage. The EV kit has two output.

The model number is a specific version of a generic that can be purchased or sampled. Status Status indicates the current lifecycle of the product. This can be one of 4 stages: Pre-Release: The model has not been released to general production, but samples may be available. Production: The model is currently being produced, and generally available for purchase and sampling. Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time. Obsolete: The specific part is obsolete and no longer available.
