Part Number: AMC1301
Dear TI Expert,
I am using AMC1301 in the design, but this question is related to the differential to single end conversion.
the signal from the output of AMC1301 send to a differential to the single end conversion. I expect the gain is 0.25( 4.99K/20K). but the result is only 0.5. as in the waveform. the blue and pink are the output of the AMC1301, measure at U23.6, U23.7. Vpp is 83.33mV. the differential input to the next amplifier is 83.33mV X 2 = 166.66mV. I expect a 0.25 gain. so I expect a 41.67mV. but I got output as the yellow trace in the waveform. it is measured 94mV, Vpp. I don't understand why the gain is close to 0.5 instead of 0.25 as in the textbook.
did I make any mistake in the calculation?
appreciate your help.
