GENERAL DESCRIPTION
The AD8003 is a triple ultrahigh speed current feedback amplifier.
Using ADI’s proprietary eXtra Fast Complementary Bipolar
(XFCB) process, the AD8003 achieves a bandwidth of 1.5 GHz
and a slew rate of 4300 V/s. Additionally, the amplifier provides
excellent dc precision with an input bias current of 50 A
maximum and a dc input voltage of 0.7 mV.
The AD8003 has excellent video specifications with a frequency
response that remains flat out to 190 MHz and 0.1% settling within
12 ns to ensure that even the most demanding video systems
maintain excellent fidelity. For applications that use NTSC video,
as well as high speed video, the amplifier provides a differential
gain of 0.05% and a differential gain of 0.01°.
The AD8003 has very low spurious-free dynamic range (SFDR)
(73 dBc @ 20 MHz) and noise (1.8 nV/√Hz). With a supply
range between 5 V and 11 V and ability to source 100 mA of
output current, the AD8003 is ideal for a variety of applications.
The AD8003 operates on only 9.5 mA of supply current per
amplifier. The independent power-down function of the AD8003
reduces the quiescent current even further to 1.6 mA.
The AD8003 amplifier is available in a compact 4 mm × 4 mm,
24-lead LFCSP_WQ. The AD8003 is rated to work over the
industrial temperature range of 40°C to +85°C.
