It delivers rail-to-rail push-pull output, operates from a single supply between 2.7 V and 5.5 V, and draws 2.5 mA per channel quiescent current. The 1 pA CMOS input bias keeps offset errors negligible with high-impedance sources. Packaged in a 14-TSSOP, it is specified over the -40°C to 125°C industrial temperature range, making it a fit for motor-drive signal conditioning, battery-powered sensor interfaces, and multi-stage filter blocks in outdoor or under-hood environments. ## Temperature grade and deployment context Rated from -40°C to 125°C, the MAX4478AUD+ is suited for industrial and automotive environments where ambient temperatures exceed the commercial 70°C ceiling. Expect it in motor-drive current-sense amplifiers, outdoor telecom line cards, and engine-bay sensor conditioning. The 14-TSSOP package is a surface-mount footprint that sits on standard FR4 without thermal vias for this power level. ## Lifecycle and sourcing posture The MAX4478AUD+ carries an Active lifecycle status and is ROHS3 compliant. No pin-compatible second source is listed in the official cross-reference, but the quad TSSOP-14 footprint is common across several op-amp families — verify pin compatibility with any alternate before committing the layout.","metaTitle":"MAX4478AUD+ General Purpose Op-Amp, 10 MHz, Rail-to-Rail","metaDescription":"MAX4478AUD+ quad op-amp: 10 MHz GBW, 3V/µs slew rate, rail-to-rail output, 2.7 V to 5.5 V supply, -40°C to 125°C.
