Figure Furthermore, new ADCs have differential inputs because they provide better common- mode rejection, noise immunity, and performance at low supply voltages. Interfacing the in-amp to the ADC requires attenuation and a level shift.

A solution is shown in Figure An optional capacitor, C1, may serve as an ant aliasing filter. This topology has five benefits. In addition to level-shifting and attenuation, very little noise is contributed to the system. R5 adds a third of the dominant noise and there- fore makes a negligible contribution to the noise of the system. The attenuator divides the noise from R3 and R4. Likewise, its noise contribution is negligible. With the help of the OP27, the AD only needs to deliver one-half of the full swing; therefore, signals can settle more quickly.

Lastly, the AD settles quickly, which is helpful because the shorter the settling time, the more bits that can be resolved when the ADC acquires data. This configuration pro- vides attenuation, a level-shift, and a convenient interface with a differential input ADC while maintaining performance. Figure 52 shows a circuit that can improve the resolution of small ac signals. Thus, smaller signals can be measured since the noise floor is lower.

V p-p input noise 0. V max input offset voltage 0. Typical CMRR vs. High CMRR over frequency allows the AD to reject wideband interference and line harmonics, greatly simplifying filter requirements. Possible applications include precision data acquisition, biomedical analysis, and aerospace instrumentation.
