Typical Applications
(Continued)
High Accuracy Sample and Hold
00564627
By closing the loop through A2, the V
OUT
accuracy will be determined uniquely by A1.
No V
OS
adjust required for A2.
T
A
can be estimated by same considerations as previously but, because of the added
propagation delay in the feedback loop (A2) the overshoot is not negligible.
Overall system slower than fast sample and hold
R1, C
C
: additional compensation
Use LF156 for
j
Fast settling time
j
Low V
OS
High Q Band Pass Filter
00564628
By adding positive feedback (R2)
Q increases to 40
f
BP
= 100 kHz
Clean layout recommended
Response to a 1Vp-p tone burst: 300μs
