... AD8515 has a very robust ESD design and can stand ESD voltages 4000 V. POWER CONSUMPTION vs. BANDWIDTH One of the strongest features of the AD8515 is the bandwidth stability over the specified temperature range while consuming small amounts of current. This effect is shown in Figure 2 through Figure 4. ...

... C = 50pF L at which it can respond to a large input signal. This frequency GAIN = 1 (known as full power bandwidth, FPBW) can be calculated from the equation FPBW for a given distortion. The FPBW of the AD8515 is shown in Figure close to 200 kHz ±2. 500pF ...

... This loop gain requirement necessitates the choice amp with a high unity gain crossover frequency, such as the AD8515. The 4.5 MHz bandwidth of the AD8515 is sufficient to accurately produce the 100 kHz center frequency, as the response in Figure 37 shows. When the op amp bandwidth is close to the center frequency of the filter, the amplifier internal phase shift causes excess phase shift at 100 kHz, altering the filter response ...
