NOTES
1Refers to small signal bandwidth.
2Output offset dependent on value for R6.
3Refer to timing diagram.
4AD2S82A only.
5These pins are referenced to +VS (i.e., HI = +12 V, LO = 0 V).
Specifications subject to change without notice.
All min and max specifications are guaranteed. Specifications in boldface are tested on all production units at final electrical test.
