Description and Introduction

Low power, precision, monolithic true rms-to-dc converter with 200 mV Full-scale Input Range The AD737 is a low power, precision, monolithic true RMS-to-DC converter manufactured by Analog Devices (AD). It is designed to compute the true RMS value of complex AC signals, including those with high crest factors. Key specifications include:

- **Input Signal Range**: The AD737 can handle input signals with a maximum peak value of ±200 mV for full-scale output.
- **Accuracy**: It offers high accuracy with a typical error of ±0.2 mV ± 0.3% of reading for sine wave inputs.
- **Bandwidth**: The device has a wide bandwidth, typically 460 kHz for 100 mV RMS input.
- **Crest Factor**: It can accurately measure signals with crest factors up to 5.
- **Power Supply**: The AD737 operates from a single power supply ranging from +2.8 V to ±16.5 V.
- **Low Power Consumption**: It typically consumes 160 µA of supply current, making it suitable for low-power applications.
- **Output**: The output is a DC voltage proportional to the RMS value of the input signal.
- **Temperature Range**: The AD737 is specified for operation over the industrial temperature range of -40°C to +85°C.

These specifications make the AD737 suitable for applications such as power measurement, instrumentation, and signal processing where accurate RMS conversion is required.
