The AD737JRZ-5 from Analog Devices is a low power, precision, monolithic true RMS-to-DC converter. It is designed to compute the true RMS value of AC and DC input voltages, maintaining high accuracy across a wide range of input waveforms, including variable duty cycle pulses and phase-controlled sine waves. This device is laser trimmed for a maximum error of ±0.2 mV ± 0.3% of reading with sine wave inputs.
Key features include a wide power supply range of ±2.5 V to ±16.5 V, a low input bias current of 25 pA maximum, and a high input impedance of 10 GΩ. It provides a 200 mV full-scale input range, which can be scaled for larger inputs. The device consumes low power, with a typical standby current of 25 μA, making it ideal for battery-powered applications like portable multimeters.
The AD737JRZ-5 is available in an 8-SOIC surface mount package. Its design, with no output buffer amplifier, significantly reduces DC offset errors, enhancing compatibility with high input impedance ADCs. This converter is suitable for upgrading the performance of non-RMS precision rectifiers, offering higher accuracy at a comparable or lower cost.
