Multi-dynamic-range sensor

摘要

A sensing system that produces a multi-dynamic range output is provided. In an illustrative embodiment, a first channel (46) and a second channel (58) receive an analog output signal from a sensing element (24). The first channel (46) provides a first digital output signal (56) that has a first dynamic range, and the second channel (58) provides a second digital output signal (68) that has a second narrower dynamic range. In some cases, the second narrower dynamic range falls within the first dynamic range, and the first digital output signal (56) may provide a first resolution and the second digital output signal (68) may provide a second greater resolution. The dynamic range and/or resolution of one or more of the first channel (46) and second channel (58) may be dynamically reconfigurable, if desired. 4 of 6 a)a) 0) f ( 0 ) ii c ii CL 0)C/) I LO vO i CoDFA 0 cU 0 L- 2w C)CD m0 0
