NOTES
1
Accuracy is specified for 0 V to 7 V rms, dc or 1 kHz sine wave input with the AD536A connected as in the figure referenced.
2
Error vs. crest factor is specified as an additional error for 1 V rms rectangular pulse input, pulsewidth = 200
μ
s.
3
Input voltages are expressed in volts rms, and error is percent of reading.
4
With 2k external pull-down resistor.
Specifications subject to change without notice.
Specifications shown in
boldface
are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. All min and max specifications are guaranteed,
although only those shown in boldface are tested on all production units.
(@ +25 C, and 15 V dc unless otherwise noted)
