Analog Devices Inc. AD636JDZ True RMS to DC Converter

The AD636JDZ is a high precision, low power, integrated true RMS-to-DC converter from Analog Devices Inc. This sophisticated component is designed to offer a complete solution for converting an alternating current (AC) input signal into its corresponding direct current (DC) value, which is directly proportional to the true root-mean-square (RMS) value, regardless of waveform shape or complexity.

Featuring a wide input bandwidth, the AD636JDZ is capable of accurately measuring signals with up to 200 kHz of bandwidth, and it can handle input levels from 0 mV to 200 mV with the crest factor of up to 5. The device is ideal for precision signal processing applications such as audio equipment, industrial control systems, power management, and instrumentation where accurate RMS measurements are critical for performance.

One of the key benefits of the AD636JDZ is its ease of use. The device requires only a single external averaging capacitor to operate, simplifying circuit design and reducing the bill of materials. Additionally, it features a high impedance input buffer, which allows direct connection to signal sources without the need for external scaling or attenuation components.

The AD636JDZ operates over a wide temperature range from -40°C to +85°C, ensuring reliable performance in a variety of environments and applications. It is also available in a small 14-lead SOIC package, making it suitable for space-constrained applications where PCB real estate is at a premium.

With its combination of accuracy, reliability, and ease of use, the AD636JDZ from Analog Devices Inc. is an excellent choice for designers looking to implement true RMS-to-DC conversion in their systems. Whether used for precision measurement or signal conditioning, the AD636JDZ delivers consistent, high-quality performance that engineers can trust.
