1. Power Supply Decoupling

The ADC150 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.

For applications with long power supply

leads an external capacitor of 10 µF on the

+/- 15V inputs and 33 µF on the +5V input is

recommended.

2. Ground

The ground connection (pin 7) should be

made as solid as possible since ground

noise can result in a loss of accuracy. Use

of a ground plane is a good approach to

maintain the full accuracy of the ADC150.

3. External Components

A .68 µF polystyrene integration capacitor

must be connected to pins 34 and 35 with a

lead length not exceeding 2".

4. Analog Inputs

In order to avoid differential noise pickup it is

recommended to use parallel adjacent lines

for the analog inputs (pins 39, 40) on PC

boards and shielded lines outside of the PC

connections.
