DESCRIPTION
The PA34 consist of a monolithic power op amp in a 7-pin T0220 package.
The wide common mode input range includes the negative rail, facilitating single supply applications. It is possible to have a “ground based” input driving a single supply amplifi er with ground acting as the “second” or “bottom” supply of the amplifier.
The output stage is also well protected. They possess internal current limit circuits. While the device is well protected, the Safe Operating Area (SOA) curve must be observed.
Proper heatsinking is required for maximum reliability.
The tab of the 7 pin plastic package is tied to –VS.
