... In this mode, the user can drive the AD8099 with a high dc source impedance and still maintain minimal output referred offset without having to use impedance matching techniques. In addition, the AD8099 can be ac-coupled while setting the bias point on the input with a high dc impedance network ...

... AD8099 requires external compensation. The amount of gain and performance needed will determine the compensation network. Understanding the subtleties of the AD8099 gives the user insight on how to exact its peak performance. Use the component values and circuit configurations shown in the Applications section as starting points for designs ...

... Kelvin the bandwidth in Hz, and R is the resistance in ohms. A simple relationship, which is easy to remember, is that a 50 Ω resistor generates a Johnson noise of 1 nV√ 25°C. The AD8099 amplifier has roughly the same equivalent noise Ω resistor. Rev Page ...

... DISABLE PIN AND INPUT BIAS CANCELLATION The AD8099 DISABLE pin performs three functions; enable, disable, and reduction of the input bias current. When the DISABLE pin is brought to within 0 the positive supply, the input bias current is reduced by an approximate factor of 60. However, the input current noise doubles to 5.2 pA/√ ...

... ADC DRIVER Ultralow noise and distortion performance make the AD8099 an ideal ADC driver. Even though the AD8099 is not unity gain stable, it can be configured to produce a net gain of +1 amplifier, as shown in Figure 71. This is achieved by combining a gain of +2 and a gain of –1 for a net gain of +1. The input range of the ADC ...

... Bypassing is critical for stability, frequency response, distortion, and PSRR performance. The 0.1 µF capacitors shown in Figure 60 through Figure 66 should be as close to the supply pins of the AD8099 as possible and the electrolytic capacitors beside them. Component Selection Smaller components less than 1206 SMT case size, offer smaller mounting pads, which have less parasitics and allow for a more compact layout ...
