Description
The CA3020 and CA3020A are integrated-circuit, multi-
stage, multipurpose, wide-band power amplifiers on a single
monolithic silicon chip. They employ a highly versatile and
stable direct coupled circuit configuration featuring wide
frequency range, high voltage and power gain, and high
power output. These features plus inherent stability over a
wide temperature range make the CA3020 and CA3020A
extremely useful for a wide variety of applications in military,
industrial, and commercial equipment.
The CA3020 and CA3020A are particularly suited for service
as class B power amplifiers. The CA3020A can provide a
maximum power output of 1W from a 12V_DC supply with a
typical power gain of 75dB. The CA3020 provides 0.5W
power output from a 9V supply with the same power gain.
Refer to AN5766 for application information.

The resistance values included on the schematic diagram have been supplied as a convenience to assist
Equipment Manufacturers in optimizing the selection of “outboard” components of equipment designs.
The values shown may vary as much as ±30%.
Intersil reserves the right to make any changes in the Resistance Values provided such changes do not
adversely affect the published performance characteristics of the device.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
