LTC1292/LTC1297
12927fb
Figure 12. “+” and “–” Input Settling Windows for the LTC1297
“–” input voltage be free of noise and settle completely
during the first CLK cycle of the conversion. Minimizing
RSOURCE– and C2 will improve settling time. If large “–”
input source resistance must be used the time can be
extended by using a slower CLK frequency. At the maximum
CLK frequency of 1MHz, RSOURCE– < 250and C2 < 20pF
will provide adequate settling.
Input Op Amps
When driving the analog inputs with an op amp it is
important that the op amp settles within the allowed time
(see Figures 11a, 11b, 11c and 12). Again the “+” and “–
” input sampling times can be extended as described
above to accommodate slower op amps. Most op amps
including the LT1797 and LT1677 single supply op amps
can be made to settle well even with the minimum settling
windows of 3.0
s for the LTC1292 or 6.0s for the
LTC1297 (“+” input) and 1
s (“–” input) that occurs at the
maximum clock rate of 1MHz. Figures 13 and 14 show
examples of both adequate and poor op amp settling.
