Hot-selling and scarce PA25 POWER DUAL OPERATIONAL AMPLIFIERS TO3 spot stock

Product Descriptions

The amplifiers consist of a monolithic dual power op amp in a 8-pin hermetic TO-3 package (PA21 and PA25)and a 12-pin SIP package (PA26). Putting two power op amps in one package and on one die results in an extremely cost effective solution  for  applications  requiring  multiple  amplifiers  per board or bridge mode configurations.

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 amplifier with ground acting as the“second” or“bottom” supply of the amplifier.

The output stages are 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.
