PA25A POWER DUAL OPERATIONAL AMPLIFIERS

PA25A POWER DUAL OPERATIONAL AMPLIFIERS

The amplifiers consist of a monolithic dual power op amp in a 8-pin hermetic TO-3 package (PA21 and PA25) and a 12pin 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 o.
