1
All minimum and maximum specifications are guaranteed. Specifications shown in boldface are tested on all production units at final electrical test and are used to
calculate outgoing quality levels.
2
Accuracy specified for 0 mV to 200 mV rms, dc or 1 kHz sine wave input. Accuracy is degraded at higher rms signal levels.
3
Measured at Pin 8 of PDIP (I
OUT
), with Pin 9 tied to common.
4
Error vs. crest factor is specified as additional error for a 200 mV rms rectangular pulse train, pulse width = 200 µs.
5
Input voltages are expressed in V rms.
