AD8000YRDZ-REEL7

1.5 GHz的超高速运算放大器 1.5 GHz Ultrahigh Speed Op Amp

Product Details

The AD8000 is an ultrahigh speed, high performance, current feedback amplifier. Using Analog Devices, Inc., 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 75 dBc at 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.

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.

The AD8000 power-down mode reduces the supply current to 1.3 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 work over the extended industrial temperature range −40°C to +125°C. A triple version of the AD8000 AD8003 is underdevelopment.
