AD536AJH

The AD536AJH is a complete monolithic integrated circuit that performs true RMS-to-DC conversion. It is designed to calculate the true RMS value of any complex input waveform containing AC and DC components, providing an equivalent DC output level. This device offers performance comparable or superior to that of more expensive hybrid or modular units.

Key Features:

• True RMS-to-DC Conversion: The AD536AJH directly computes the true RMS value of the input waveform, which is directly related to the signal power and is more useful than the average rectified value.
• High Accuracy: The device is laser-trimmed for high accuracy, with a maximum error of ±0.5% for the AD536AJ variant. This ensures precise measurements even with complex input waveforms.
• Wide Bandwidth: The AD536AJH has a wide bandwidth that extends its measurement capability to 300 kHz with less than 3 dB errors for signal levels greater than 100 mV. This makes it suitable for a wide range of applications that require high-frequency measurements.
• Crest Factor Compensation: The device includes a crest factor compensation scheme that allows measurements with a 1% error at crest factors up to 7. This ensures accurate measurements even with input waveforms that have high peak-to-average ratios.
• Auxiliary dB Output Pin: An important feature of the AD536AJH is its auxiliary dB output pin, which was not available in previous RMS converters. The logarithm of the RMS output signal is output through a separate pin, supporting dB conversion with a usable dynamic range of 60 dB.
• Low Power Consumption: The AD536AJH has a low power consumption of 1.2 mA quiescent current, making it suitable for various remote controllers and battery-powered instruments.
• Single- or Dual-Supply Operation: The device can operate with either a single or dual power supply, providing flexibility in power management.
• Temperature Range: The AD536AJH operates over a temperature range of -55°C to +125°C (for the AD536AS variant), making it suitable for various environmental conditions.

Applications:

• Automated test equipment (ATE)
• Control systems and instrumentation
• Any application requiring precise RMS-to-DC conversion of complex input waveforms

In summary, the AD536AJH is a versatile and high-performance true RMS-to-DC converter that offers high accuracy, wide bandwidth, crest factor compensation, and low power consumption. Its compact monolithic integrated circuit design and auxiliary dB output pin make it an ideal choice for various applications that require precise RMS measurements.
