In a manifold absolute pressure sensor application, a strain
gauge is mounted on the intake manifold in the engine unit.
Manifold pressure causes the sensing resistors, R1, R2, R3
and R4 to change. The resistors change in a way such that
R2 and R4 increase by the same amount R1 and R3 de-
crease. This causes a differential voltage between the input
of the amplifier. The gain of the amplifier is adjusted by R
Spice Macromodel
A spice macromodel is available for the LMC6492/4. This
model includes accurate simulation of:
and many other characteristics as listed on the macromodel
disk.
