1.5 GHz, Ultra-High Speed Op Amp with Power-Down
The AD8000 is an ultra-high speed, high performance, current feedback amplifier. Using ADI's proprietary eXtra Fast Complementary 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 75dBc @ 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 applications including high speed instrumentation.
The AD8000 power-down mode reduces the supply current to 1.3mA. The amplifier is available in a tiny 8-lead LFCSP package, as well as 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.
