Typical Single-Supply Applications (Continued)
In
Figure 23 dielectric absorption and leakage is minimized by using a polystyrene or polyethylene hold capacitor. The droop rate
is primarily determined by the value of C
H and diode leakage current. The ultra-low input current of the LMC6484 has a negligible
effect on droop.
The LMC6484’s high CMRR (85 dB) allows excellent accuracy throughout the circuit’s rail-to-rail dynamic capture range.
The low pass filter circuit in
Figure 25 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 LMC6484 ultra-low input current. The ultra-low 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.
