ADC enables temperature-compensated weigh-scale measurements

Posted on Mar 4, 2013

You can provide temperature compensation in weigh-scale applications by simultaneously measuring both the temperature of the bridge and the primary output of the bridge transducer. Traditionally, an integrated multiplexer connects multiple input variables to a single sigma-delta ADC. Each time the multiplexer switches the input, the ADC must flush the digital filter of all data pertaining to the previous channel. Before the new data becomes valid, the system must account for the settling time and latency, reducing the maximum throughput rate.
