TECHNICAL NOTES
1. All ground pins should be tied together and connected to system analog
ground as close to the package as possible. It is recommended to use
a ground plane under the device and solder ground pins directly to it.
Take care to ensure that no ground potentials can exist between
ground pins. A single +5V supply can be used for both
+5V Digital Supply (pin 1) and +5V Analog Supply (pin 7).
2. External 0.1μF to 4.7μF tantalum bypass capacitors are required in
critical applications.
3. A logic 1 on S/H puts the unit in the sample mode. A logic 0 puts the
unit in hold mode.
4. Gain and offset adjusting can be accomplished using the external cir-
cuitry shown in Figure 2. Adjust offset with a 0V input. Adjust gain with a
±FS input. Adjust so that the output in the hold mode matches the input.
