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
