Application Circuits
(Continued)
This low-pass filter circuit can be used as an anti-aliasing fil-
ter with the same supply as the A/D converter. Filter designs
can also take advantage of the LMC6492/4 ultra-low input
current. The ultra-low input current yields negligible offset er-
ror even when large value resistors are used. This in turn al-
lows the use of smaller valued capacitors which take less
board space and cost less.
Dielectric absorption and leakage is minimized by using a
polystyrene or polypropylene hold capacitor. The droop rate
is primarily determined by the value of C
and diode leakage
current. Select low-leakage current diodes to minimize
drooping.
In a manifold absolute pressure sensor application, a strain
gauge is mounted on the intake manifold in the engine unit.
