The AD8014 is a low power, high performance 400 MHz amplifier. It features low cost, high speed, low noise, low distortion, and is suitable for applications such as photo-diode preamps, cameras, handheld devices, etc.
The AD8014 is a revolutionary current‑feedback operational amplifier offering 400 MHz -3 dB bandwidth, 4000 V/µs slew rate, and a fast 24 ns settling time. It operates from +4.5 V to +12 V supplies, draws only 1.15 mA quiescent current, and provides very low voltage (3.5 nV/√Hz) and current (5 pA/√Hz) noise.
Its high‑speed performance and low distortion make it suitable for video signal drivers, photodiode pre‑amps in CD/DVD devices, handheld instruments, and other power‑sensitive high‑speed systems. The datasheet includes detailed specifications, absolute maximum ratings, ordering information, and mechanical dimensions.
| -3 dB Bandwidth | 400 MHz (small‑signal, G=+1) |
|---|---|
| Slew Rate | 4000 V/µs |
