I have seen power op amps available in small metal hybrid packages or monolithic amplifiers in small plastic packages. How are your products different?
Hybrid amplifiers are generally expensive and are often meant for military applications. You must mount the hybrid to a heat sink to be of any practical use in most cases. Once the hybrid is mounted to a heat sink the total amplifier is not small. The total volume utilized includes not only the amplifier but also the footprint of the heat sink as well. Our amplifiers can dissipate more power as built on their heat sinks than most hybrids can when mounted on an infinite heat sink. Monolithic amplifiers, while small, also cannot handle the power dissipation of our amplifiers. In the end it?s the power dissipation capability of the amplifier that determines the usefulness of an amplifier in a power application. Our new line of compact power amps approach the footprint of the small hybrid amplifiers with a footprint only 40mm square. This makes our compact amplifiers only slightly longer and wider than a hybrid TO3 package, and our amplifiers include the heat sink in the same footprint.
