NOTES:
1. Power Supply Decoupling
2. Ground
3. External Components
4. Analog Inputs
For applications with long power supply
leads an external capacitor of 10 mF on the
+/- 15V inputs and 33 mF on the +5V input is
recommended.
noise can result in a loss of accuracy. Use
of a ground plane is a good approach to
maintain the full accuracy of the ADC100.
must be connected to pins 34 and 35 with a
lead length not exceeding 2".
boards and shielded lines outside of the PC
The ADC100 has internal 0.1µF decoupling
capacitors for all power supply inputs. The
internal decoupling capacitors are adequate
for applications with relatively short power
supply leads (approx. 5") or if additional
capacitors are located on a circuit board.
The ground connection (pin 7) should be
made as solid as possible since ground
A 0.68 µF polystyrene integration capacitor
In order to avoid differential noise pickup it is
recommended to use parallel adjacent lines
for the analog inputs (pins 39, 40) on PC
connections.
