Neuchâtel, May 23rd - XEMICS was recently awarded grand prize ''Winner of
the Best of Sensor Expo'' out of 100 finalists.
The ZoomingADC™ feature that supports its series of XE8000 microcontrollers was selected for its most innovative characteristics. The feature enables users to zoom in on a portion of the signal, which, in turn, then applies the full resolution of the A/D converter. The award is co-sponsored by Sensors Magazine and Advanstar Communications both of which are important actors in the Sensors Industry.
''We are certainly most pleased to be tied to such a group through this award'', said Roland Heer, CEO of XEMICS SA. He went on to say, ''This prize represents a considerable achievement for our company and in particular signals the industry's recognition of our company's efforts. We are most satisfied with this result.''
The ZoomingADC™ is part of XEMICS' XE88LC05 and XE88CL01 microcontroller; its function amplifies the input signal before converting it to a 16-bit code. The microcontroller includes all the hardware required for direct interface with piezoresistive sensors. The CPU controls the data acquisition process and computes any necessary linerisation. Signal output is made through the UART, the parallel port, or one of the D/A converters. The ZoomingADC™, the data acquisition block of the microcontroller, makes it possible to measure a small signal with a large offset with maximum resolution. Its function is analogous to that of a camera zoom lens. The user selects that part of the signal with the desired data, ''zooms in on it,'' and applies the full resolution of the A/D
converter to that portion. For instance, a given A/D converter has a resolution of 1000 points. If therefore, the input signal has full scale of 2 V, then the resolution is 2 mV ( 2 V/1000). If the interesting part of the signal is only 20 mV, zooming in on it yields a final resolution of 20 uV (20 mV/1000. By sharing the gain and offset compensation over three stages, the ZoomingADC™ can compensate for large offsets on a small signal without saturation or resolution losses. A differential signal path allows the converter to capture both single and differential signals; it accommodates single-ended signals by adding controlled offset.
Price availability for the XE88LC05 is at 9$ for 10K, and
the XE88LC01 at 8$ for 10K.
