Using ADI’s proprietary eXtra Fast Com- plementary Bipolar (XFCB) process, the amplifier can achieve a small signal bandwidth of 1.5 GHz and a slew rate of 4100 V/µs. The AD8000 has low spurious-free dynamic range (SFDR) of 75 dBc @ 20 MHz and input voltage noise of 1.6 nV/√Hz. The AD8000 can drive over 100 mA of load current with minimal distortion. The amplifier can operate on +5 V to ±6 V. These specifications make the AD8000 ideal for a variety of applica- tions, including high speed instrumentation. With a differential gain of 0.02%, differential phase of 0.01°, and 0.1 dB flatness out to 170 MHz, the AD8000 has excellent video specifications, which ensure that even the most demanding video systems maintain excellent fidelity.

Large Signal Frequency Response The AD8000 power-down mode reduces the supply current to 1.3 mA. The amplifier is available in a tiny 8-lead LFCSP pack- age, as well as in an 8-lead SOIC package. The AD8000 is rated to work over the extended industrial temperature range (−40°C to +125°C). A triple version of the AD8000 (AD8003) is under- development. |
