Product Overview: AD636JH from Analog Devices Inc.

The AD636JH is a high-precision, low-power, true RMS-to-DC converter manufactured by Analog Devices Inc., a leader in high-performance semiconductors. This integrated circuit is designed to offer accurate and reliable conversion of complex AC input signals to their true root-mean-square (RMS) DC equivalent, which is essential for accurate measurement in a wide range of applications.

Featuring a wide bandwidth of up to 1 kHz, the AD636JH is capable of handling signals with up to 200 mV rms of input range, making it suitable for audio, industrial, and medical applications where precision signal processing is critical. Its exceptional accuracy, with a maximum error of ±0.3% of reading plus ±1 mV, ensures that the output closely represents the true RMS value of the input signal, even when the waveform is distorted or noisy.

The device operates on a single supply voltage ranging from 5 V to 30 V, or dual supplies of ±2.5 V to ±15 V, providing flexibility in system design. The low power consumption of the AD636JH, typically 1.2 mA, is an advantage for portable and battery-powered applications, where power efficiency is a priority.

With its high impedance input and no requirement for external trims to achieve full specified performance, the AD636JH is easy to use and can be implemented in a system with minimal additional components. The device also features a dB output capability, allowing direct decibel-scaled readings of the input voltage.

Encased in a hermetic TO-100 package, the AD636JH is built to withstand harsh environments and provides reliable performance over a wide temperature range of -55°C to +125°C. This robustness, combined with its precision, makes it an ideal choice for high-end applications in test and measurement, industrial control systems, and professional audio equipment.

As a product of Analog Devices Inc., the AD636JH benefits from the company's reputation for quality and support, ensuring that designers can incorporate this RMS-to-DC converter into their systems with confidence.
