A curve labeled “Aperture Time” has been included for sampling
conditions where the input is steady during the sampling period, but
may experience a sudden change nearly coincident with the “HOLD”
command. This curve is based on a 1mV error fed into the output.
A second curve, “Hold Settling Time,” indicates the time required for
the output to settle to 1mV after the “HOLD” command.
Digital Feedthrough
Fast rise time logic signals can cause hold errors by feeding
externally into the analog input at the same time the amplifier is put
into the hold mode. To minimize this problem, board layout should
keep logic lines as far as possible from the analog input. Grounded
guarding traces may also be used around the input line, especially if
it is driven from a high impedance source. Reducing high amplitude
logic signals to 2.5V will also help.
Logic signals also couple to the hold capacitor. This hold capacitor
should be guarded by a PC card trace connected to the
sample-and-hold output. This will also minimize board leakage.
SPECIAL NOTES
1. Not all definitions herein defined are measured parametrically for
the NE5537, but are legitimate terms used in sample-and-hold
systems.
2. Reference should be made to Design Engineering, Volumes 23
(Nov. 8, 1978), 25 (Dec. 6, 1978) and 26 (Dec. 20, 1978) for
articles written by Eugene Zuch of Datel Systems, Inc., for a
further discussion of sample-and-hold circuits.
3. Reference also made to National Semiconductor Corporation’s
Special Functions Data Book (1976).
