Description

The AD736JNZ is a monolithic true RMS-to-DC Converter, belonging to the category of Electronic Component- RMS-to-DC Converters. This low power converter is accurate and cost-effective and can be widely used in many applications where precision rectifiers need to be upgraded to non-RMS.

Specifications and features

• Full-scale input range: 200mV RMS
• Input impedance: 1012 Ω
• Bias current: 25pA maximum
• Accuracy: ±0.3 mV ± 0.3% of reading
• Power supply range: +2.8V, -3.2V to ±16.5V
• Supply current: 200µA maximum
• Output type: Buffered voltage output
• No external trims needed for specified accuracy

Application Scenarios

The AD736JNZ can be widely used in various applications where non-RMS precision rectifiers needs to be upgraded. This can include signal processing in power supplies, motor controls, communications and instrumentation systems, audio level metering, and waveform analysis.

Comparison

• High accuracy in measuring a wide range of input waveforms, including variable duty-cycle pulses and triac-controlled sine waves
• Low power consumption
• No external trims needed for specified accuracy
• Small size and cost-effective

• Limited RMS conversion with signal crest factors up to 5 only
• Can only handle small input range (200mV RMS)
• Requires external input attenuator for larger inputs
