The AD637KRZ is a precision true-root-mean-square (RMS) to DC converter with ratios, gains and temperature coefficients better than 0.05% over a 4:1 input dynamic range. It is a precision RMS-to-DC converter designed to accurately and economically replace conventional dual-bridge and Anderson bridge converters, providing ideal performance for general-purpose and industrial applications. The AD637KRZ is a versatile building block for many industrial and medical applications, including power quality, motor controllers, temperature and flow controllers and frequency converters, and is ideal for applications where large (20:1) dynamic range is needed.

The AD637KRZ works by providing a high-precision, true RMS detector to measure input signals in the presence of gain, phase and linearity errors. This helps to eliminate the need for manual calibration or complicated compensation networks when using the device in a variety of high-performance industrial applications. It also provides high-impedance input buffering, allowing measurements of common-mode signals without affecting their value. In addition, it features a wide operating range across temperature, allowing the converter to function in extreme temperature conditions without sacrificing accuracy.

The AD637KRZ works by providing an internal voltage reference and high-precision RMS-to-DC detector. The voltage reference provides an input for the device which is used for measuring the RMS value of the input signal. The output of the detector is then used to convert the input signal from an RMS value to a DC voltage. The resulting DC voltage is then buffered and filtered, providing a high-precision output. This output can then be used for a variety of applications, including control and monitoring.

In addition, the AD637KRZ features a wide range of features which make it an ideal choice for high-performance applications. It features an adjustable zero offset of up to 32.768V, allowing the converter to be used in applications with high dynamic range requirements. The AD637KRZ also has a programmable detection rate, allowing the user to adjust the response speed of the device. Finally, the device is designed to be extremely low noise, allowing it to function in noise-sensitive environments without sacrificing accuracy.

The AD637KRZ is an ideal choice for a variety of applications which require a true RMS-to-DC converter. It is a versatile solution for applications which require high precision, low power consumption and a wide operating range across temperature. Additionally, the AD637KRZ can be used in a variety of industrial applications, such as motor controllers, temperature and flow controllers and frequency converters.
