The AD8065/AD8066 are high-performance, 145 MHz FastFET op amps with 1 pA input bias current, low cost, high speed, low noise, wide supply voltage range, single-supply and rail-to-rail output, low offset voltage, high common-mode rejection ratio, excellent distortion specifications, low power, and small packaging. They are qualified for automotive applications.
The AD8065 (single) and AD8066 (dual) are voltage‑feedback, FET‑input operational amplifiers offering 145 MHz (AD8065) and 120 MHz (AD8066) bandwidth, 180 V/µs slew rate, and rail‑to‑rail output. They feature ultra‑low input voltage noise (7 nV/√Hz) and input bias current (6 pA), making them suitable for high‑speed, low‑noise applications such as video buffers and photodiode pre‑amps.
These amplifiers are qualified for automotive use, operate from 5 V to 24 V (single‑supply or dual‑supply), and are available in SOIC‑8, SOT‑23‑5, and MSOP‑8 packages. The datasheet provides detailed specifications, absolute maximum ratings, typical performance curves, layout and grounding guidelines, and ordering information.
