Using ZoomingADC to Adapt the ADC to the Sensor, and not the Other Way Around!

From Semtech Corp.
 

 
There is a wide variety of sensing elements available on the market to accommodate different types of measurements. One thing most of these sensors have in common is that their output signal is less than optimal, and low-cost versions of the sensors introduce quite a large spread of gain and offset variation into the production of a sensing device. A conventional way to overcome this spread is to add amplification ICs and to laser trim the amplification settings before connecting the sensing element to the ADC, or to buy higher cost, more sensitive and better-controlled sensor elements. Another way to overcome the gain and offset variation is to use Semtech's ZoomingADC data acquisition device, which combines the advantages of over-sampled ADCs with an embedded amplification stage to measure low cost sensor elements with the highest resolution.
