Other Parts Discussed in Thread: AMC1301
Hello
Please guide me through this query.
I am using AMC1301-Q1 for motor current sensing using shunt resistor. The datasheet of AMC1301 suggests inherent Vcmout = 1.44 V. But according to sba229 application note "Interfacing a Differential-Output (Isolated) Amplifier to a Single-Ended Input ADC" , if we use differential mode only, the output contains the AC signal of 8.2 * +/-250mV with DC offset of 1.44.
If we convert the differential output to a single ended output, an external Vcm is used to provide DC offset. In this case, does the inherent 1.44 V offset gets bypassed or added to the external Vcm? (Figure 3 in SBA229)
