With a 4 MHz gain-bandwidth product and a 3.5 V/µs slew rate, it handles audio-band filtering, sensor buffering, and control-loop conditioning without the overhead of a high-speed part. The rail-to-rail output stage means the signal swing reaches the supply rails — useful when running from a single 5 V rail and you need every millivolt of headroom for an ADC input. ## Analog performance that matters for precision front-ends Input bias current is 0.2 pA typical — this is a CMOS-input stage, so the bias error stays negligible even with 10 MΩ source impedances, making it a natural fit for photodiode or pH probe amplifiers. Input offset voltage is 600 µV max — not an auto-zero grade, but tight enough for general-purpose signal chains where you calibrate the zero at the system level. Each amplifier draws 1.15 mA supply current, and the output can source or sink 140 mA — enough to drive a headphone load or a small relay coil directly. ## Supply range and temperature grade Operates from a single 5 V supply up to 16 V, or split supplies up to ±8 V — the 5 V minimum span means it works on a standard 5 V logic rail without a boost converter. Rated for -40°C to +125°C, so it survives under-hood temperatures in automotive sensor interfaces or industrial enclosures near a motor drive. ## Package and sourcing reality The 8-MSOP package is hand-solderable with a fine tip or hot air — the 0.65 mm pitch is forgiving enough for rework, and the tube packaging keeps the parts aligned for pick-and-place feeders.","metaTitle":"AD8666ARMZ Dual Rail-to-Rail Op-Amp, 4 MHz, 8-MSOP","metaDescription":"AD8666ARMZ dual general-purpose op-amp by Analog Devices. 4 MHz GBW, 3.5 V/µs slew rate, rail-to-rail output, 0.2 pA bias.
