The rail-to-rail output stage swings within millivolts of both supply rails, maximizing dynamic range in single-supply 5 V to 16 V systems. With a gain-bandwidth product of 1.5 MHz and slew rate of 2V/µs, it handles low-frequency precision loops without sacrificing settling time. ## Temperature range and package — industrial-grade in a compact footprint The 8-LFCSP-WD (3x3 mm) package with exposed pad pulls heat into the PCB ground plane, keeping junction temperature in check even with both channels driving 37 mA loads. The small footprint — 3x3 mm — saves board space compared to SOIC-8 alternatives, though the pad requires a thermal via pattern for full dissipation. ## Design-in note: supply decoupling and thermal pad The 5 V to 16 V supply range covers common rails — 5 V, 9 V, 12 V, 15 V — without an extra regulator. Place a 0.1 µF ceramic close to each supply pin and a 10 µF bulk cap nearby. MSL 3 out of the bag — bake before reflow if the moisture-barrier bag has been open past the floor-life window.","metaTitle":"AD8639ACPZ-REEL7 Zero-Drift Op-Amp, 2V/µs Slew Rate, 8-LFCSP","metaDescription":"ADI AD8639ACPZ-REEL7 dual chopper op-amp: 3 µV offset, 1 pA bias, 1.5 MHz GBW, -40°C to 125°C.
