The AD736BRZ-R7 is a monolithic integrated compensated rms-to-dc voltage converter. RMS-to-DC converters are used to convert an alternating current (AC) input signal into a direct current (DC) output signal, and they are helpful in many industrial and consumer applications. This article will discuss the application field and working principle of the AD736BRZ-R7.

Application field

Powered by both single- and dual-supply operation, the AD736BRZ-R7 is applicable in a number of applications, such as power amplifiers, audio equipment, medical equipment, computer systems, and many more. It can be used to convert an alternating current input signal into a direct current output signal without having to make any additional hardware modifications.

The AD736BRZ-R7 is compliant with the low-voltage peak-current protection amplitude specified in the 2nd edition of IEC 60601-1 and offers a wide range of safety features. This makes it suitable for use in healthcare and medical applications, where safety is of utmost importance.

The AD736BRZ-R7 is rated for operation between -40°C to 85°C and has a single-cycle settling time of 11μs. This makes it suitable for use in high-performance and high-speed applications. It can be used to replace bulky analog solutions, as it offers superior performance and improved power efficiency.

Working principle

The AD736BRZ-R7 operates on a simple differential amplifier circuit, which is followed by a peak-detection circuit. The input signal is fed into the differential amplifier circuit, which amplifies the signal. This amplified signal is then fed into the peak-detection circuit, which measures the peak value of the input signal and generates a corresponding direct-current output.

The peak-detection circuit makes use of the capacitance of a special peak-detection capacitor and the resistance of a fixed resistor. The difference between the voltage of the capacitor and the voltage of the fixed resistor is measured and used to generate the corresponding DC output.

The output of the peak-detection circuit is filtered by a low-pass filter to remove any noise from the direct-current output. This ensures that the output remains stable over the entire operating temperature range of the AD736BRZ-R7.

The AD736BRZ-R7 has integrated compensation for both the differential amplifier and the peak-detection circuit. This ensures that the device can accurately detect the peak value of a wide range of input signals, including those with high levels of noise.

The AD736BRZ-R7 can be used in a variety of applications, including power amplifiers, audio equipment, medical equipment, computer systems, and many more. It provides superior performance, improved power efficiency, and a wide range of safety features, which make it suitable for use in healthcare and medical applications. The integrated compensation feature ensures that it can accurately detect the peak value of a wide range of input signals, and the single-cycle settling time allows it to operate at high speeds.
