ABSTRACT:
The input voltage from a fuel tank level sender is processed by an anti-slosh circuit which has a short time constant during a fast acquire operation and a longer time constant during normal operation. The slew rate of the output voltage provided to a gauge is determined by the clock rate of an up/down counter which is determined by switched resistances and a small valued capacitor. Either analog or digital anti-slosh outputs are provided.
