Adjustable Analog Filter

There are a variety of applications where signals from different sources (for example, sensors) are sensed with one ADC. Such systems require an analog multiplexer with analog filters for each channel, because each signal source may have its own set of filter requirements (for example, different cutoff frequencies). An alternative space-efficient and cost-efficient solution is to use one tunable analog filter for all channels. The SLG47004 IC solves this task perfectly.
