Application Information
The HA-5320 has the uncommitted differential inputs of an
op amp, allowing the Sample and Hold function to be
combined with many conventional op amp circuits. See the
Intersil Application Note AN517 for a collection of circuit
ideas.
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
EXT
is used, then a noise
bandwidth capacitor of value 0.1C
EXT
should be connected
from pin 8 to ground. Exact value and type are not critical.
The hold capacitor C
EXT
should have high insulation
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.
Layout
A printed circuit board with ground plane is recommended
for best performance. Bypass capacitors (0.01F to 0.1F,
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
