General-purpose single op-amp for low-power signal chains
The Analog Devices AD8541ARZ is a single-channel general-purpose operational amplifier in an 8-SOIC surface-mount package. It delivers a 1 MHz gain-bandwidth product with a 0.92 V/µs slew rate, drawing only 45 µA of supply current. The rail-to-rail output stage lets it swing close to the supply rails, which matters when running from a 2.7 V to 5.5 V single supply. Input bias current is 4 pA, and input offset voltage is 1 mV. The -40°C to 125°C operating range covers industrial and automotive under-hood environments — motor-drive feedback, sensor conditioning, or battery-monitoring loops where the board sees temperature cycling.
What the ratings mean for the BOM
The 1 MHz GBW and 0.92 V/µs slew rate set the usable bandwidth for small-signal and large-signal paths.
Package and mounting
The AD8541ARZ comes in an 8-SOIC package (0.154" body width, 3.90 mm) — a standard footprint that fits most PCB layouts without a respin. Surface-mount assembly is straightforward for reflow or wave-solder processes.
