GainAmp Signal Coupling
and Configurations
Common op-amp configurations include both nonin-
verting and inverting amplifiers. Figures 5–8 show vari-
ous single and dual-supply circuit configurations.
Single-supply systems benefit from a midsupply bias
on the noninverting input (provided internally on
MAX4175/MAX4275), as this produces a quiescent DC
level at the center of the rail-to-rail output stage signal
swing. For dual-supply systems, ground-referenced
signals may be DC-coupled into the inverting or non-
inverting inputs.

/ 2 bias options cou-
ples power-supply noise directly to the op amp’s nonin-
verting input. To minimize high-frequency power-supply
noise coupling, add a 1μF to 0.1μF capacitor from IN+
to ground to create a lowpass filter (Figure 6). The low-
pass filter resulting from the internal bias resistors and
added capacitor can help eliminate higher frequency
power-supply noise coupling through the noninverting
input.
