8.2.6 Low-Side Current-Monitor
A low-side current shunt monitor is shown in Figure 29. The R1 through R6 resistors are operational resistors used to isolate the 16-bit ADS1115-Q1 converter from the noise of the digital I2C bus.
NOTE:
1% resistors provide adequate common-mode rejection at small ground-loop errors.
