Typical Applications (continued)
The high CMRR (82 dB) of the LMC6482 allows excellent accuracy throughout the rail-to-rail dynamic capture
range of the circuit.

The low-pass filter circuit in Figure 77 can be used as an anti-aliasing filter with the same voltage supply as the
A/D converter.
Filter designs can also take advantage of the LMC6482 ultralow input current. The ultralow input current yields
negligible offset error even when large value resistors are used. This in turn allows the use of smaller valued
capacitors which take less board space and cost less.
