Acquisition Time
The time required following a “sample” command, for the
output to reach its final value within
±
0.1% or
±
0.01%. This is
the minimum sample time required to obtain a given accu-
racy, and includes switch delay time, slewing time and set-
tling time.
Charge Transfer
The small charge transferred to the holding capacitor from
the inter-electrode capacitance of the switch when the unit is
switched to the HOLD mode. Charge transfer is directly pro-
portional to sample-to-hold offset pedestal error, where:
Charge Transfer (pC) = C
H
(pF) x Offset Error (V)
Aperture Time
The time required for the sample-and-hold switch to open,
independent of delays through the switch driver and input
amplifier circuitry. The switch opening time is the interval
between the conditions of 10% open and 90% open.
Hold Step Error
Hold Step Error is the output error due to Charge Transfer
(see above). It may be calculated from Charge Transfer,
using the following relationship:
HOLD STEP (V) =
CHARGE TRANSFER (pC)
HOLD CAPACITANCE (pF)
See Performance Curves.
Effective Aperture Delay Time (EADT)
The difference between propagation time from the analog
input to S/H switch, and digital delay time between the Hold
command and opening of the switch.
EADT may be positive, negative or zero. If zero, the S/H
amplifier will output a voltage equal to V
IN
at the instant the
Hold command was received. For negative EADT, the output
in Hold (exclusive of pedestal and droop errors) will
correspond to a value of V
IN
that occurred before the Hold
command.
Aperture Uncertainty
The range of variation in Effective Aperture Delay Time.
Aperture
Uncertainty
(also
Uncertainty, Aperture Time Jitter, etc.) sets a limit on the
accuracy with which a waveform can be reconstructed from
sample data.
called
Aperture
Delay
Drift Current
The net leakage current from the hold capacitor during the
hold mode. Drift current can be calculated from the droop
rate using the formula:
I
D
(pA) = C
H
(pF) x
V
T
(V/s)
