Where:

• i = 1 to 2 for dual and 1 to 4 for quad

Unused Amplifiers

It is recommended that any unused amplifiers in a dual and

a quad package be configured as a unity gain follower. The

inverting input should be directly connected to the output

and the non-inverting input tied to the ground plane.

Power Supply Bypassing and Printed Circuit

Board Layout

The ISL24020 can provide gain at high frequency. As with

any high-frequency device, good printed circuit board layout

is necessary for optimum performance. Ground plane

construction is highly recommended, lead lengths should be

as short as possible and the power supply pins must be well

bypassed to reduce the risk of oscillation. For normal single

connected in parallel, placed in the region of the amplifier.

One 4.7µF capacitor may be used for multiple devices. This

same capacitor combination should be placed at each

supply pin to ground if split supplies are to be used.
