AD536AJHZ AD536AJHZ

AD536A is an integrated monolithic true RMS-to-DC converter for precise alternating current signal measurement. JHZ refers to hermetically sealed 14-lead ceramic dual in-line through-hole package, supplied in tube packaging for laboratory development and industrial instrument assembly.

This all-in-one semiconductor device calculates the true root-mean-square value of arbitrary waveform AC signals and converts the result into stable DC output voltage without complex external mathematical circuits. It supports signals with a crest factor up to 6, compatible with sine waves, square waves, irregular pulse signals and noisy waveforms commonly seen in industrial measurement scenarios.

The operating power supply includes single supply and dual bipolar supply modes, with bipolar supply ranging from ±5 V to ±15 V. The total conversion error is controlled within 0.2% under standard operating conditions, with outstanding temperature stability and long-term drift performance. Only one external averaging capacitor is required to set the averaging time constant, which balances measurement accuracy and response speed flexibly.

The input accepts wide voltage amplitude ranges, and the internal circuit features high input impedance to avoid loading effects on preceding signal sources. The output stage can directly drive resistive loads and high-impedance voltmeters. Quiescent power consumption remains low during continuous operation, suitable for long-term unattended measuring instruments.

Housed in 14-pin hermetic ceramic DIP through-hole package. The fully sealed metal-ceramic structure isolates internal circuitry from moisture, dust and corrosive ambient gases, delivering superior anti-aging performance for long-term field service. Moisture Sensitivity Level is MSL3, and all reflow soldering work must be finished within 168 hours after unpacking the original vacuum package. Tube packaging is adopted to facilitate manual welding, breadboard circuit construction and small-batch instrument production.

Operating temperature range spans 0 °C to +70 °C. It runs reliably inside desktop laboratory instruments, panel-mounted industrial meters and indoor signal detection equipment under mild temperature variations. Fabricated via lead-free production processes, the component complies with international RoHS environmental regulations. The complete integrated architecture eliminates numerous discrete operational amplifiers and trimming components, simplifying the analog measurement circuit design significantly.
