【简 介】:he sensor output voltage span seldom equals the analog
o-digital converter (ADC) input voltage span. Sensor data
s lost and/or ADC dynamic range is not fully utilized
ecause the spans are unequal, start at different DC voltages
r both. In Figure 1(a) the spans are equal but offset.
his situation requires level shifting to move the sensor
utput voltage up by one volt so the spans match. In
igure 1(b) the spans are unequal, but no offset exists.
his situation requires amplification of the sensor output
o match the spans. When the spans are unequal and off-
et, as is often the case, level shifting and amplification
re required to match the spans.
