DISCUSSION OF
SPECIFICATIONS
THROUGHPUT NONLINEARITY
Throughput nonlinearity is defined as total Hold mode,
nonadjustable, input to output error caused by charge offset,
gain nonlinearity, 1ms of droop, feedthrough, and thermal
transients. It is the inaccuracy due to these errors which
cannot be corrected by offset and gain adjustments. Through-
put nonlinearity is tested with a 1000pF holding capacitor,
10V input changes, 10
μ
s acquisition time, and 1ms Hold
time (see Figure 1).
GAIN ACCURACY
Gain Accuracy is the difference between input and output
voltage (when in the Sample mode) due to amplifier gain
errors.
DROOP RATE
Droop Rate is the voltage decay at the output when in the
Hold mode due to storage capacitor, FET switch leakage
currents, and output amplifier bias current.
FEEDTHROUGH
Feedthrough is the amount of the input voltage change that
appears at the output when the amplifier is in the Hold mode.
APERTURE TIME
Aperture Time is the time required to switch from Sample to
Hold. The time is measured from the 50% point of the mode
control transition to the time at which the output stops
tracking the input.
ACQUISITION TIME
Acquisition Time is the time required for the sample/hold
output to settle within a given error band of its final value
when the mode control is switched from Hold to Sample.
