Part Details:

Low Cost, Low Power, True RMS-to-DC Converter AD736 FEATURES FUNCTIONAL BLOCK DIAGRAM Computes 8k C 1 8 COM AD736 True rms value C Average rectified value FULL WAVE Absolute value V RECTIFIER 8k IN 2 7 +VS INPUT Provides AMPLIFIER 200 mV full-scale input range (larger inputs with input CF 3 rms CORE 6 OUTPUT attenuator) BIAS SECTION OUTPUT High input impedance: 1012 AMPLIFIER Low input bias current: 25 pA maximum ­VS 4 5 CAV High accuracy: ±0.3 mV ± 0.3% of reading 0014- RMS conversion with signal crest factors up to 5 0083 Wide power supply range: +2.8 V, -3.2 V to ±16.5 V Figure 1. Low power: 200 mA maximum supply current The AD736 allows the choice of two signal input terminals: a Buffered voltage output high impedance FET input (1012 ) that directly interfaces with No external trims needed for specified accuracy High-Z input attenuators and a low impedance input (8 k) that AD737--an unbuffered voltage output version with allows the measurement of 300 mV input levels while operating chip power-down also available
