Another output-caused fault is shown in Figure 13. The
output transitions are initially correct but end in a ringing
condition. The key to the solution here is the ringing. What
is happening is caused by an output lead that is too long.
The output lead looks like an unterminated transmission
line at high frequencies and reflections occur. This ac-
counts for the abrupt reversal of direction on the leading
edge and the ringing. If the comparator is driving TTL this
may be acceptable, but other loads may not tolerate it. In
this instance, the direction reversal on the leading edge
might cause trouble in a fast TTL load. Keep output lead
lengths short. If they get much longer than a few inches,
terminate with a resistor (typically 250 to 400).
200ns-0.01% Sample-and-Hold Circuit
Figure 14’s circuit uses the LT1016’s high speed to
improve upon a standard circuit function. The 200ns
acquisition time is well beyond monolithic sample-and-
hold capabilities. Other specifications exceed the best
commercial unit’s performance. This circuit also gets
around many of the problems associated with standard
sample-and-holdapproaches,includingFETswitcherrors
and amplifier settling time. To achieve this, the LT1016’s
high speed is used in a circuit which completely abandons
traditional sample-and-hold methods.
Important specifications for this circuit include:
Acquisition Time
<200ns
Common Mode Input Range
±3V
Droop
1V/s
Hold Step
2mV
Hold Settling Time
15ns
Feedthrough Rejection
>>100dB
When the sample-and-hold line goes low, a linear ramp
starts just below the input level and ramps upward. When
therampvoltagereachestheinputvoltage,A1shutsoffthe
ramp, latches itself off and sends out a signal indicating
sampling is complete.
