PA169

PA169 is an Apex Microtechnology dual high-voltage power operational amplifier in a 52-pin Power Quad (20 x 20 mm) package — it packages two independent 200 V amplifier channels, each rated 1 A continuous and 4 A peak with 35 V/µs slew rate, for bridge drives, differential piezo actuators and dual-axis servo outputs, dissipating up to 52 W across both amplifiers. Apex states the family is currently in volume production; the PA169A (2 A per channel) is the separate higher-current order code on the same product page. Selection advice: the dual format pays off in bridge configurations, where the pair drives a floating load differentially and doubles the effective output swing — if your load is single-ended and needs only one channel, the single PA167 on this site is the simpler socket. Thermal design must consider both channels loaded simultaneously, since the 52 W figure is a package total, and cross-channel coupling through the shared package argues for a symmetric layout. Parameters verified against Apex Microtechnology documentation.
