ABSTRACT:
Techniques for adjusting the dynamic range of an A/D converter in response to various conditions are disclosed. A value output by the A/D converter is utilized to determine if the A/D converter is operating at or above its current dynamic range capabilities (i.e., the A/D converter is potentially “saturated” at its current dynamic range setting). If potentially saturated, the dynamic range of the A/D converter may be increased. If not, the dynamic range of the A/D converter may be decreased or may be unchanged. Alternately, an upcoming or enacted change in the gain settings of one or more gain stages that condition the analog signal input to an A/D converter may be used as a condition that results in an adjustment to the dynamic range of the A/D converter.
