SNOS674G November 1997 – April 2020 LMC6482
Low power, single supply data acquisition system solutions are provided by buffering the ADC12038 with the LMC6482 (Figure 56). Capable of using the full supply range, the LMC6482 does not require input signals to be scaled down to meet limited common-mode voltage ranges. The LMC4282 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.
NOTE:Operating from the same supply voltage, the LMC6482 buffers the ADC12038 maintaining excellent accuracy.
