... Exposure to absolute maximum rating conditions for extended periods may affect device reliability. MAXIMUM POWER DISSIPATION The maximum safe power dissipation in the AD8007/AD8008 packages is limited by the associated rise in junction temperature ( the die.

... THEORY OF OPERATION The AD8007 (single) and AD8008 (dual) are current feedback amplifiers optimized for low distortion performance. A simplified conceptual diagram of the AD8007 is shown in Figure 51. It closely resembles a classic current feedback amplifier comprised of a complementary emitter-follower input stage, a pair of signal mirrors, and a diamond output stage. However, in the case of ...

... AD8007/AD8008 Whenever physical layout considerations prevent the decoupling scheme shown in Figure 53, the user can connect one of the high frequency decoupling capacitors directly across the supplies and connect the other high frequency decoupling capacitor to ground (see Figure 54 499Ω 10µ 0.1µ ...

... When they are not parallel, they help reduce unwanted positive feedback. EXTERNAL COMPONENTS AND STABILITY The AD8007/AD8008 are current feedback amplifiers and first order, the feedback resistor determines the bandwidth and stability. The gain, load impedance, supply voltage, and input impedances also have an effect ...
