... Currents should be limited through these diodes less by using a series limiting resistor. PACKAGING INNOVATION The ADA4899-1 is available in both a SOIC and an LFCSP, each of which has a thermal pad that allows the device to run cooler, thereby increasing reliability. To help avoid routing around the pad when laying out the board, both packages have a dedicated feedback pin on the opposite side of the package for ease in connecting the feedback network to the inverting input ...

... ADA4899-1 APPLICATIONS UNITY-GAIN OPERATION The ADA4899-1 schematic for unity-gain configuration is nearly a textbook example (see Figure 46). The only exception is the small 24.9 Ω series resistor at the noninverting input. The series resistor is only required in unity-gain configurations; higher gains negate the need for the resistor. In Table 4, it can be seen that the overall noise contribution of the amplifier and the 24.9 Ω ...

... The ultralow noise and distortion performance of the ADA4899-1 makes it an excellent candidate for driving 16-bit ADCs. The schematic for a single-ended input buffer using the ADA4899-1 and the AD7677 MSPS, 16-bit ADC, is shown in Figure 49. Table 5 shows the performance data of the ADA4899-1 and the AD7677. ...

... The returns for the input, output terminations, bypass capacitors, and R be kept as close to the ADA4899-1 as possible. The output load ground and the bypass capacitor grounds should be returned to the same point on the ground plane to minimize parasitic trace inductance, ringing, and overshoot and to improve distortion performance ...
