NOTES
1
Operation down to 0.02 GHz is possible.
2
Mean and Standard Deviation specifications are available in Table I.
3
See TPC 9 for plot of Input Impedance vs. Frequency.
4
This parameter is guaranteed but not tested in production. Limit is –3 sigma from the mean.
5
Response time in a closed-loop system will depend upon the filter capacitor (C
FLT
) used and the response of the variable gain element.
6
This parameter is guaranteed but not tested in production. Maximum specified limit on this parameter is the +6 sigma value.
Specifications subject to change without notice.
