1. A method for operating an analog frontend (AFE), comprising:

  • selecting one of multiple sensors coupled to the AFE;

    receiving input sensor data from the sensor;

    computing features for the sensor based on the input sensor data, the features representing selected operating condition information of the AFE for the sensor;

    determining one of multiple discrete operating states of the AFE for the sensor based on the computed features; and

    dynamically adjusting operation of the AFE to interface with the sensor based on the determined operating state, including controlling a configuration of the AFE that controls how the AFE receives the input sensor data from the sensor.
