8.3.1 Data Acquisition Systems
Low power, single supply data acquisition system solutions are provided by buffering the ADC12038 with the
LMC6484 (Figure 73). Capable of using the full supply range, the LMC6484 does not require input signals to be
scaled down to meet limited common-mode voltage ranges. The LMC6484 CMRR of 82 dB maintains integral
linearity of a 12-bit data acquisition system to ±0.325 LSB. Other rail-to-rail input amplifiers with only 50 dB of
CMRR will degrade the accuracy of the data acquisition system to only 8 bits.
