Apex Microtechnology PA74/A & PA76/A Class C Power Amplifiers

Apex Microtechnology PA74/A and PA76/A Class C Power Amplifiers are dual-power operational amplifiers (op-amps) featuring 2.5A x 2 of continuous output current on 5V to 40V single supplies. The PA74/A and PA76/A Amplifiers utilize monolithic and hybrid technologies by placing two ICs in an electrically isolated, hermetically sealed, 8-pin TO-3 metal package. The result is a cost-effective solution for applications requiring multiple amplifiers per board or bridge-mode configurations.

The ICs that comprise the PA74/A and PA76/A are designed with dual input and output stages to achieve the desired input and output characteristics. The input stage utilizes a dual power amplifier on a single IC that drives the output stages. The output stages are configured in a non-inverting unity gain buffer configuration. The output stages of the amplifier are also compensated for stability but are not recommended for use as unity gains followers.

The "A" variants of the Apex Microtechnology PA74/A and PA76/A Class C Power Amplifiers provide 3A x 2 of output current and enhanced performance in the areas of offset voltage and voltage swing. The "M" variants are non-compliant military-grade versions.
