Apex Microtechnology PA74A Power Dual Operational Amplifier

PA74A from Apex Microtechnology is a dual power operational amplifier designed for high-current, single-supply operation. Each amplifier channel delivers 2.5 A of continuous output current, with a peak capability around 3 A when powered from a 5–40 V supply, enabling direct drive of demanding loads without an external driver stage. The device supports substantial power dissipation — about 36 W per amplifier and up to 60 W when both halves are driven — making thermal management important in high-duty applications. Quiescent current for the pair runs roughly 18–40 mA total, and the case temperature range extends to 85 C. The PA74A belongs to Apex's PA74/PA76 family of Power Dual Operational Amplifiers, which are designed to deliver high current in a compact package.
