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 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 R
S
is not required. Resistors R
F
and R
are kept low to minimize their contribution to the overall noise
performance of the amplifier.
