Overview
Data Sheet
FEATURES
Computes True rms value Average rectified value Absolute value
Provides 200 mV full-scale input range (larger inputs with input scaling) Direct interfacing with 3½ digit CMOS analog-to-digital converters (ADCs) High input impedance: 1012 Ω Low input bias current: 25 pA maximum High accuracy: ±0.
2 mV ± 0.
3% of reading RMS conversion with signal crest factors up to 5 Wide power supply range: ±2.
5 V to ±16.
5 V Low power: 25 μA (typical) standby current No external trims needed for specified accuracy
The AD737 output is negative going; the AD736 is a positive output-going version of the same basic device
