Apex Microtechnology

Apex Microtechnology builds high-voltage, high-current power operational amplifiers for motor drive, piezoelectric actuation, test equipment and industrial control. The profiles here cover its 200 V power op amp line in the 52-pin Power Quad package: the PA167 and PA169 single- and dual-channel parts at 1 A continuous (4 A peak) per channel, and the PA168 at 4 A continuous (10 A peak), with A-grade variants doubling the continuous rating. Apex announced the three base parts in volume production in August 2026. Because the base and A-grade codes share one package and pinout, the ordering code is the only thing separating a 1 A design from a 2 A one — confirm the exact variant and the thermal design against your dissipation budget before ordering.

Sourcing notes for Apex Microtechnology parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
