In automotive applications, it is used for battery management, control of electric and hybrid vehicles, engine control, power steering, collision detection, and passive start systems.

Working Principle of AD736JR

The AD736JR performs RMS to DC conversion by converting the input analog signal into a fixed internal reference voltage and then comparing it to the output of the integrated current source. If the input signal is higher than the fixed reference, the current source will be driven to increase its output to match the reference voltage. On the other hand, if the input signal is lower than the fixed reference, the current source will be driven to decrease its output to match the reference voltage. This process is then repeated at each sampling cycle, thus ensuring accurate and efficient RMS to DC conversion. The AD736JR also features noise/ripple reduction circuitry, which minimizes the errors in measurements due to interference from external sources and improves the accuracy of the waveform\'s output. Additionally, its fast-settling output stage provides instant, accurate responses to changing waveforms, making it ideal for industrial, automotive, medical, and other high-speed applications.

Conclusion

The AD736JR PMIC – RMS to DC converter is a highly advanced, low voltage, monolithic converter designed to provide high performance, accuracy and reliability.
