... Communication or Video Test Systems Portable Medical Instruments PRODUCT DESCRIPTION The AD8005 is an ultralow power, high-speed amplifier with a wide signal bandwidth of 170 MHz and slew rate of 280 V/ s. This performance is achieved while consuming only 400 A of quiescent supply current. These features increase the operating time of high-speed battery-powered systems without reducing dynamic performance ...

... 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 AD8005 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 ...

... A given value of capacitance causes much less ringing when the amplifier is used with a higher noise gain. The capacitive load drive of the AD8005 can be increased by adding a low valued resistor in series with the capacitive load. Introducing a series resistor tends to isolate the capacitive load from the feedback loop thereby diminishing its influence ...

... Amp 1 is removed and the signal can be fed directly into Amp 1. Layout Considerations In order to achieve the specified high-speed performance of the AD8005 you must be attentive to board layout and component selection. Proper R design techniques and selection of compo- F nents with low parasitics are necessary. ...

... In order to drive an rms output voltage the output must deliver a current of 3 the feedback net- work. Increasing the size of the resistor network by a factor shown in Figure 33 will reduce this current to 360 A. The closed loop bandwidth will however decrease to 20 MHz.
