The AD736BR is an integrated circuit designed by Analog Devices Inc., renowned for its precision in converting complex AC voltage waveforms into their true root-mean-square (RMS) DC equivalent. This high-performance component is essential in applications where accurate RMS readings are crucial, regardless of waveform shape due to its ability to accurately measure both sinusoidal and non-sinusoidal, or distorted, waveforms.

Key Features:

• Wide Bandwidth: Capable of measuring signals with up to 200 kHz, the AD736BR provides flexibility for a wide range of applications.
• Low Power: The device operates with a quiescent current of 1.5 mA max for the BR version, which is suitable for battery-powered devices and energy-efficient applications.
• High Accuracy: It offers a high accuracy of ±0.3% of reading for a 60 Hz sinusoidal input, which ensures precise measurements.
• Input Voltage Range: Designed to accept input voltages of 200 mV to 200 V when used with an external attenuator or preamplifier.
• Flexible Power Supply: The AD736BR can operate from a single +5 V supply or dual ±15 V supplies, providing versatility in system design.
• Compact Package: Available in an 8-pin SOIC package, the device is suitable for space-constrained applications.

Applications:

• Power measurement in communication systems
• Audio signal processing
• Industrial process control
• Instrumentation
• AC motor controls

The AD736BR's exceptional performance makes it an ideal choice for designers seeking an RMS-to-DC converter that can handle a variety of AC signals, including those from industrial, audio, and communication sources. Its ease of use and small footprint allow for seamless integration into existing and new designs alike, making it a valuable addition to any electronic system requiring reliable and accurate RMS measurements.
