PRODUCT DESCRIPTION
The ABA3101 is a monolithic IC intended for use in
applications requiring high linearity, such as Cellular
Telephone Base Station Driver Amplifiers, CATV Fiber
Receiver and Distribution Amplifiers, CATV Drop Am-
S33 Package
Modified 16 Pin SOIC
with Heat Slug
plifiers, CATV Set Top Boxes, and Home Gateways.
Offered in a modified 16 lead surface mount SOIC
package with a heat slug, it is well suited for use
in amplifiers where small size, reduced component
count, and high reliability are important.

Stresses in excess of the absolute ratings may cause permanent damage.
Functional operation is not implied under these conditions. Exposure
to absolute ratings for extended periods of time may adversely affect
reliability.
Notes:
1. Pins 1, 2, 3, 6, 7 and 8 should be AC-coupled. No external DC bias should be
applied.
2. Pin 9 should be AC-grounded. No external DC bias should be applied.
