Description

The AD8000 is an ultrahigh speed, high performance, currentfeedback amplifier. Using Analog Devices, Inc., proprietaryeXtra Fast Complementary Bipolar (XFCB) process, the amplifiercan achieve a small signal bandwidth of 1.5 GHz and a slewrate of 4100 V/μs.The AD8000 has low spurious-free dynamic range (SFDR) of75 dBc at 20 MHz and input voltage noise of 1.6 nV/√Hz. TheAD8000 can drive over 100 mA of load current with minimaldistortion. The amplifier can operate on +5 V to ±6 V. Thesespecifications make the AD8000 ideal for a variety of applications,including high speed instrumentation.With a differential gain of 0.02%, differential phase of 0.01°, and0.1 dB flatness out to 170 MHz, the AD8000 has excellent videospecifications, which ensure that even the most demandingvideo systems maintain excellent fidelity.The AD8000 power-down mode reduces the supply current to1.3 mA. The amplifier is available in a tiny 8-lead LFCSP package,as well as in an 8-lead SOIC package. The AD8000 is rated to workover the extended industrial temperature range (−40°C to +125°C).A triple version of the AD8000 (AD8003) is underdevelopment.Applications Professional video High speed instrumentation Video switching IF/RF gain stage CCD imaging
