Other Parts Discussed in Thread: OP07 , ADS8284 , THS4521 I am using ADS8284IB which is a 18 bit +- 2.5 LSB integral linearity ADC. With this ADC I am not getting +- 2.5 LSB accuracy. I have used some hardware to convert bipolar single ended signal in to…
Hello Seema,
In the schematic, since the negative side of the resistor network is grounded, the common mode of the CxP and CxM inputs cannot be kept at Vref/2 as required by the ADS8284.
The resistance network in Figure 71 has the following transfer …
