AD637
Specifications shown in bold are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels.
All minimum and maximum specifications are guaranteed, although only those shown in boldface are tested on all production units.
Accuracy specified 0 V rms to 7 V rms dc with AD637 connected, as shown in
Nonlinearity is defined as the maximum deviation from the straight line connecting the readings at 10 mV and 2 V.
Error vs. crest factor is specified as additional error for 1 V rms.
Input voltages are expressed in volts rms. Percent is in % of reading.
With external 2 kΩ pull-down resistor tied to −V
