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 resistor is equivalent to the noise of a single 87 Ω resistor.
Figure 47 shows the small signal frequency response for the
unity-gain amplifier shown in Figure 46.

RECOMMENDED VALUES FOR VARIOUS GAINS
Table 4 provides a handy reference for determining various
gains and associated performance. For noise gains greater than
one, the Series Resistor RS is not required. Resistors RF and RG
are kept low to minimize their contribution to the overall noise
performance of the amplifier.
