The AD737 is a low power, high precision, monolithic digital True RMS converter providing a 200 mV full-scale input range (larger inputs with input attenuator), direct interfacing with 3½ digit CMOS ADCs, high input impedance (1012 Ω), low input bias current (25 pA maximum), high accuracy (±0.2 mV ± 0.3% of reading), wide power supply range (±2.5 V to ±16.5 V), and low power consumption (160 μA maximum supply current). No external trims are required for specified accuracy. A general-purpose, buffered voltage output version is also available (AD736).
