HA-5330
Application Information
The HA-5330 has the uncommitted differential inputs of an
op amp, allowing the Sample/Hold function to be combined
with many conventional op amp circuit ideas. See the Harris
Application Note AN517 for a collection of circuit ideas.
Layout
A printed circuit board with ground plane is recommended
for best performance. Bypass capacitors (0.01µF to 0.1µF,
ceramic) should be provided from each power supply
terminal to the Supply GND Terminal on pin 11.
Output Stage
The HA-5330 output circuit does not include short circuit
protection, and consequently its output impedance remains
low at high frequencies. Thus, the step changes in load
current which occur during an A/D conversion are absorbed
at the S/H output with minimum voltage error. A momentary
short circuit to ground is permissible, but the output is not
designed to tolerate a short of indefinite duration.
Glossary of Terms
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
accuracy, and includes switch delay time, slewing time and
settling time.
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 that interval
between the conditions of 10% open and 90% open.
Hold Step Error
Hold step error is the output shift due to charge transfer from
the sample to the hold mode. It is also referred to as “offset
step” or “pedestal error”.
Typical Applications
The HA-5330 is configured as a unity gain noninverting
amplifier by simply connecting the output (pin 7) to the
inverting input (pin 14). As an input device for a fast succes-
sive - approximation A/D converter, it offers an extremely
high throughput rate. Also, the HA-5330’s pedestal error is
adjustable to zero by using an Offset Adjust potentiometer
(10K to 50K) center tapped to V-.

The ideal ground connections are pin 11 (Supply Ground)
directly to the system Supply Common, and pin 12 (Signal
Ground) directly to the system Signal Ground (Analog
Ground).
Hold Capacitor
The HA-5330 includes a 90pF MOS hold capacitor, sufficient
for most high speed applications (the Electrical Specifica-
tions section is based on the internal capacitor).

Effective Aperture Delay Time (EADT)
The difference between the digital delay time from the Hold
command to the opening of the S/H switch, and the propaga-
tion time from the analog input to 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 called Aperture Delay
Uncertainty, Aperture Time Jitter, etc.) sets a limit on the
accuracy with which a waveform can be reconstructed from
