The AD736JRZ-R7 from Analog Devices is a low-power, precision monolithic true RMS-to-DC converter designed for accurate conversion of AC voltage waveforms to DC voltage. It features a 200 mV rms full-scale input range and maintains high accuracy with a maximum error of ±0.3 mV ± 0.3% of reading for sine wave inputs. This device is capable of measuring a wide range of input waveforms, including variable duty-cycle pulses and triac-controlled sine waves, with signal crest factors up to 5.
Operating from a wide power supply range of +2.8 V to ±16.5 V, the AD736JRZ-R7 consumes a low supply current of only 160 µA, making it suitable for battery-powered applications. It boasts a high input impedance of 10¹² Ω and a low input bias current of 25 pA maximum. The converter includes a buffered voltage output and requires no external trims for specified accuracy.
Packaged in an 8-SOIC surface mount case, the AD736JRZ-R7 is designed for ease of integration into compact designs. Its low cost and small size make it an ideal upgrade for non-RMS precision rectifiers, offering superior accuracy at a competitive price point.
