Description

The AD737 operates by first squaring the input signal, averaging it, and then taking the square root, thereby providing a true RMS measurement. It is designed to handle both AC and DC inputs and can be configured to operate over a wide range of frequencies and signal amplitudes. The output is a DC voltage that is directly proportional to the RMS value of the input signal. The AD737 is known for its high accuracy, low power consumption, and wide dynamic range, making it suitable for a variety of signal measurement and monitoring applications.

Features

  • True RMS-to-DC Conversion: Provides accurate RMS measurement of complex waveforms, not just sine waves.
  • Wide Input Signal Range: Handles input signals ranging from 1 mV to several volts RMS.
  • Low Power Consumption: Operates with minimal power, making it suitable for portable and battery-powered devices.
  • High Accuracy: Typically provides ±0.3% accuracy over a wide range of input levels.
  • Low Nonlinearity: Ensures precise conversion with nonlinearity typically less than ±0.2%.
  • Wide Frequency Range: Effective over a wide frequency range, typically from 0.1 Hz to 10 kHz.
  • Single or Dual Supply Operation: Can operate from a single supply of 2.8V to 16V or dual supplies from ±2V to ±18V.
  • High Input Impedance: Minimizes loading on the input signal source.
  • Compact Packaging: Available in small, easy-to-use DIP and SOIC packages.

Specifications

  • Input Voltage Range: 0 to ±300 mV RMS (internal scaling) or up to ±7 V RMS with external scaling.
  • Output Voltage Range: Proportional to the RMS value of the input.
  • Accuracy: Typically ±0.3% at 1V input, 1 kHz sine wave.
  • Nonlinearity: Typically ±0.2% of reading.
  • Frequency Range: 0.1 Hz to 10 kHz (higher with reduced accuracy).
  • Supply Voltage: Single supply of +2.8V to +16V or dual supplies from ±2V to ±18V.
  • Supply Current: Typically 170 µA at 5V.
  • Operating Temperature Range: -40°C to +85°C.
  • Package Types: Available in 8-pin DIP and SOIC packages.

Applications

  • AC Voltage and Current Measurement: Provides precise RMS measurement for monitoring AC signals in power systems.
  • Audio Signal Measurement: Measures audio signal levels in various audio equipment and devices.
  • Power Monitoring: Used in systems that monitor and control electrical power, where RMS measurements are necessary.
  • Signal Conditioning: Conditions signals in data acquisition systems, ensuring accurate amplitude measurement.
  • Instrumentation: Suitable for use in precision measurement equipment where RMS values are critical.
  • Portable Test Equipment: Due to its low power consumption, it’s ideal for handheld and portable instruments.
