DC Gain (Non-Inverting)

The non-inverting DC voltage gain for the configuration

shown in Figure 1 is:

The normalized gain plots in the

Typical Performance

Characteristics section show different feedback resistors,

mended for obtaining the highest bandwidth with minimal

the non-inverting input.

Accuracy of DC gain is usually limited by the tolerance of

DC Gain (Unity Gain Buffer)

Unity gain buffers are easily designed with a current-

feedback amplifier as long as the recommended feed-

Parasitic capacitance at the inverting node may require a

flat frequency response.
