AD637JR General Description

The AD637JR combines the functionality of a precision voltage reference and a true rms-to-dc converter, offering a wide dynamic range of 90 dB and the ability to measure signals with crest factors up to 3. It operates over a temperature range of -40°C to +85°C and has a supply voltage range of ±4 V to ±18 V, making it suitable for use in diverse environments. The device's output voltage is proportional to the rms value of the input voltage signal, with a high input impedance of 10 MΩ and a low input bias current of 5 pA, minimizing errors when measuring small signals. It boasts a high accuracy of 0.3% over the full temperature range, ensuring precise measurements, and a fast response time of 400 µs, suitable for real-time monitoring applications. The AD637JR is housed in an 8-lead SOIC package, making it easy to integrate into existing systems, and is an ideal solution for applications requiring precision voltage referencing and rms-to-dc conversion
