AD736JRZ Datasheet

Other Power Management


The AD736JRZ is a low power, precision, monolithic true rms-todc converter. It is laser trimmed to provide a maximum error of ±0.3 mV ± 0.3% of reading with sine wave inputs. Furthermore,it maintains high accuracy while measuring a wide range of input waveforms, including variable duty-cycle pulses and triac (phase)-controlled sine waves. The low cost and small size of this converter make it suitable for upgrading the performance of non-rms precision rectifiers in many applications. Compared to these circuits, the AD736 offers higher accuracy at an equal or lower cost. AD736JRZ Features • Converts an ac voltage waveform to a dc voltage and then• converts to the true rms, average rectified, or absolute value• 200 mV rms full-scale input range (larger inputs with input attenuator)• High input impedance: 1012 Ω• Low input bias current: 25 pA maximum• High accuracy: ±0.3 mV ± 0.3% of reading• RMS conversion with signal crest factors up to 5• Wide power supply range: +2.8 V, −3.2 V to ±16.5 V• Low power: 200 μA maximum supply current• Buffered voltage output• No external trims needed for specified accuracy• Related device: the AD737—features a power-down control• with standby current of only 25 μA; the dc output voltage is negative and the output impedance is 8 kΩ
