AD536AJQ: True RMS-to-DC Converter IC

The AD536AJQ is a monolithic integrated circuit that performs true RMS-to-DC conversion. This device is capable of computing the true RMS value of any complex input waveform that contains both AC and DC components, providing an equivalent DC output level.

Key Features:

1. True RMS Conversion:

   • The AD536AJQ directly computes the true RMS value of the input waveform, which is a more accurate representation of signal power compared to average rectified values.

2. High Accuracy:

   • The device offers high accuracy, with performance comparable or superior to more expensive hybrid or modular units. The specific accuracy grade may vary depending on the variant, but typically, it is within a small error margin.

3. Wide Bandwidth:

   • The AD536AJQ has a wide bandwidth that extends its measurement capability to high frequencies. This makes it suitable for applications that require measurements of high-frequency signals.

4. Crest Factor Compensation:

   • The device includes a crest factor compensation scheme that allows measurements with a small error margin (e.g., 1%) at crest factors up to a certain level (e.g., 7). This ensures accurate measurements even with input waveforms that have high peak-to-average ratios.

5. Auxiliary dB Output Pin:

   • An important feature of the AD536AJQ is its auxiliary dB output pin. This pin provides the logarithm of the RMS output signal, allowing for dB conversion with a useful dynamic range.

6. Low Power Consumption:

   • The AD536AJQ has a low quiescent current, making it suitable for applications where power consumption is a concern.

7. Single- or Dual-Supply Operation:

   • The device can operate with either a single or dual power supply, providing flexibility in power management.

8. Temperature Range:

   • The AD536AJQ operates over a wide temperature range, making it suitable for various environmental conditions.

Applications:

The AD536AJQ is suitable for a wide range of applications that require precise RMS-to-DC conversion of complex input waveforms. These include automated test equipment, control systems, instrumentation, and any application where accurate RMS measurements are critical.

In summary, the AD536AJQ is a high-performance true RMS-to-DC converter IC that offers high accuracy, wide bandwidth, crest factor compensation, an auxiliary dB output pin, low power consumption, and flexible power supply options. Its compact monolithic integrated circuit design makes it an ideal choice for various demanding applications.
