Key Features
- True RMS computation for accurate conversion of sinusoidal, triangular, and pulse waveforms to DC
- Wide supply range from ±3.2 V to ±16.5 V suits battery-powered and benchtop instrument designs
- 0.35% maximum linearity error ensures high accuracy in precision power and energy measurement systems
- Low 200 µA quiescent supply current minimises power dissipation in portable handheld meters
Applications
The AD736KR-REEL is widely used in true-RMS digital multimeters and clamp meters where accurate conversion of distorted AC mains waveforms to a DC reading is required regardless of crest factor. It is also integrated into industrial energy meters and power-quality analysers to measure RMS current through non-linear loads such as variable-frequency drives and switch-mode power supplies operating below 5 kHz. Audio test equipment and low-frequency signal-level indicators also employ this device for VU-meter and level-detection circuits that require precision RMS amplitude measurement.

Frequently Asked Questions
What bandwidth does AD736KR-REEL support for accurate RMS conversion, and which waveform types does it handle?
AD736KR-REEL provides accurate true RMS conversion up to 5 kHz bandwidth, making it suitable for audio-frequency and power-line signals at 50 Hz or 60 Hz. It correctly converts sinusoidal, triangular, square, and other non-sinusoidal waveforms rather than relying on an average-responding approximation, which avoids the 11% error typical of average-responding rectifiers on square waves.
What supply voltage range does AD736KR-REEL require, and can it run from a single 5 V rail?
AD736KR-REEL is specified for dual supplies of ±3.2 V minimum to ±16.5 V maximum, nominally ±5 V. It does not support single-supply operation without a mid-rail bias network; however, with a simple voltage divider creating a virtual ground at 2.5 V, it can operate from a 5 V to 9 V single supply with reduced dynamic range below 1 V RMS input.
How does the AD736KR-REEL compare with an average-responding AC converter for measuring distorted industrial currents?
Average-responding AC converters introduce errors of 5% to 40% when measuring non-sinusoidal waveforms because they assume a pure sine wave crest factor of 1.414. AD736KR-REEL computes the true RMS value directly, limiting the error to its 0.35% linearity specification even on waveforms with crest factors up to 10, making it far more accurate for variable-frequency drive and switch-mode supply current measurements.
Why is the reel tape-and-reel packaging of AD736KR-REEL preferred for high-volume automated PCB assembly?
Tape-and-reel format holds 2500 units per reel for the 8-pin SOIC, enabling uninterrupted pick-and-place machine operation across large production batches without manual tube-reloading pauses. This reduces changeover time per reel to under 2 minutes and lowers handling-induced ESD risk compared to loose tube packaging, cutting per-unit assembly cost at volumes above 500 pieces per run.
