NOTES
1
Typical values are at 25
°
C and nominal supply, unless otherwise noted.
2
Full-scale = 11 V.
3
Full-scale range = 22 V.
4
Guaranteed by design and characterization but not subject to production test.
5
Force control amplifier dominates slew rate and settling time.
6
Operational with
±
12 V supplies, force/measure range is reduced to
±
8.5 V.
Specifications subject to change without notice.
