Application Information
The HA-5320 has the uncommitted differential inputs of an
op amp, allowing the Sample and Hold function to be
Intersil 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 Ground terminal on pin 13.
The ideal ground connections are pin 6 (SIG. Ground)
directly to the system Signal Ground, and pin 13 (Supply
Ground) directly to the system Supply Common.
13. Observe the “hold step” voltage V
14. Compute charge transfer: Q = V

Hold Capacitor
The HA-5320 includes a 100pF MOS hold capacitor,
sufficient for most high speed applications (the Electrical
Specifications section is based on this internal capacitor).
Additional capacitance may be added between pins 7 and
11. This external hold capacitance will reduce droop rate at
the expense of acquisition time, and provide other trade-offs
as shown in the Performance Curves.
If an external hold capacitor C
bandwidth capacitor of value 0.1C
from pin 8 to ground. Exact value and type are not critical.
The hold capacitor C
resistance and low dielectric absorption, to minimize droop
errors. Polystyrene dielectric is a good choice for operating
temperatures up to 85°C. Teflon® and glass dielectrics offer
good performance to 125°C and above.
