The AD8014 is a low power high performance amplifier with features such as low cost, high speed, low noise, and low distortion.
The AD8014 is a 400 MHz, low‑power, high‑performance current‑feedback operational amplifier. It offers a 1.15 mA quiescent current, 4000 V/µs slew rate, and very low noise (3.5 nV/√Hz voltage, 5 pA/√Hz current). The device operates from a 4.5 V to 12 V supply and provides up to 50 mA output current with low distortion.
Typical applications include photodiode preamplifiers for CD/DVD drives, video drivers for series‑terminated cables, and other high‑speed consumer‑electronics circuits. The datasheet includes functional block diagrams, detailed electrical specifications, absolute maximum ratings, and mechanical dimensions.
