... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8004 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... THEORY OF OPERATION The AD8004 is a member of a new family of high speed current- feedback (CF) amplifiers offering new levels of bandwidth, distortion, and signal-swing capability vs. power. Its wide dynamic range capabilities are due to both a complementary high speed bipolar process and a new design architecture. The AD8004 is basically a two stage (Figure 30) rather than the conventional one stage design ...

... The fine scale gain flatness and –3 dB bandwidth is affected by R selection as is normal of current feedback amplifiers. FEEDBACK With the exception of gain = +1, the AD8004 can be adjusted for either maximal flatness with modest closed-loop bandwidth or for mildly peaked-up frequency response with much more bandwidth. Figure 8 shows the effect of three evenly spaced R changes upon gain = +1 and gain = +2 ...

... The AD8004 is well positioned for driving this new class of A/D converters. Figure 12 shows a circuit that uses an AD8004 to drive an AD876, a single supply, 10-bit, 20 MSPS A/D converter that requires only 140 mW. Using the AD8004 for level shifting and driving, the A/D exhibits no degradation in performance com- pared to when it is driven from a signal generator ...
