Abstract
Enhanced multi-channel sensor interfaces with programmable signal adjustments are provided. An example sensor interface may include an input selector that selects one or more sensor signals from a plurality of sensor signals based on input selection control signal; an offset generator that generates an offset signal based on an offset control signal; and a programmable signal adjuster that adjusts at least one selected sensor signal based on the generated offset signal and a signal adjustment control signal. The sensor interface may include a control interface unit that generates the input selection control signal, the offset control signal, and the signal adjustment control signal. The sensor interface may include a comparator that compares output of the programmable signal adjuster with a reference signal, and provides based on the comparison an output configured for use in performing offset correction. The programmable signal adjuster may generate a number of selectable gains.
