The AD8000 is an ultrahigh speed, high performance, current feedback amplifier from Analog Devices. It uses ADI's proprietary eXtra Fast Com- plementa mixed technology, and has a maximum slew rate of up to 4100 V/µs in the 1.5 GHz frequency range and an input voltage noise of 1.6 nV/√Hz.
The AD8000 is a 1.5 GHz, current‑feedback operational amplifier built on Analog Devices' XFCB process. It offers a very high slew rate, low input noise, and high output current capability, making it suitable for high‑speed instrumentation, video switching, RF gain stages, and CCD imaging.
The device is available in 8‑lead LFCSP and SOIC packages, operates from a 4.5 V to 12 V supply, and includes a power‑down mode that reduces quiescent current to about 1.3 mA. Absolute‑maximum ratings and thermal specifications are provided for reliable design across an extended industrial temperature range.
| -3 dB Bandwidth (G=+1) | 1.5 GHz |
|---|---|
| Input Voltage Noise (100 kHz) | 1.6 nV/√Hz |
| Maximum Output Current | 100 mA |
| Supply Voltage Range | 4.5 V to 12 V |
| Quiescent Supply Current (typical) | 13.5 mA |
| Power‑Down Current (typical) | 1.3 mA |
The typical quiescent supply current is 13.5 mA.
In power‑down mode the device draws about 1.3 mA.
The input voltage noise is 1.6 nV/√Hz at 100 kHz.
At a gain of +1 the –3 dB bandwidth is 1.5 GHz.
