... 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 AD8002 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 ...

... AD8002 THEORY OF OPERATION A very simple analysis can put the operation of the AD8002, a current feedback amplifier, in familiar terms. Being a current feedback amplifier, the AD8002’s open-loop behavior is expressed as transimpedance, ∆V /∆ The open-loop transim- O –IN Z pedance behaves just as the open-loop voltage gain of a voltage feedback amplifier, that is, it has a large dc value and decreases at roughly 6 dB/octave in frequency ...

... The AD8002 also drives four back-terminated loads (two each), as shown in Figure 9, with equally impressive performance (0.01%, 0.07°). Another important consideration is isolation between loads in a multiple load application. The AD8002 has more than isolation at 5 MHz when driv- ing two 75 Ω back-terminated loads ...

... The AD8002 is well suited for driving high-speed analog-to- digital converters such as the AD9058. The AD9058 is a dual 8-bit 50 MSPS ADC. In Figure 10, the AD8002 is shown driv- ing the inputs of the AD9058 which are configured for ranges. Bipolar input signals are buffered, amplified (–2×), and offset (by 1 ...

... Single-Ended-to-Differential Driver Using an AD8002 The two halves of an AD8002 can be configured to create a single-ended-to-differential high-speed driver with a –3 dB bandwidth in excess of 200 MHz, as shown in Figure 11. Although the individual op amps are each current feedback, the overall architecture yields a circuit with attributes normally associated with voltage feedback amplifiers, while offering the speed advan- tages inherent in current feedback amplifiers ...

... AD8002 Layout Considerations The specified high-speed performance of the AD8002 requires careful attention to board layout and component selection. Proper R design techniques and low parasitic component selec- F tion are mandatory. The PCB should have a ground plane covering all unused por- tions of the component side of the board to provide a low impedance ground path ...
