7.3.4.2 Output Behavior in Case of Input Common-Mode Overrange
If INN or INP is disconnected from the shunt resistor, the input bias current of the AMC1306M25E drives the disconnected terminal towards the positive supply rail, and the common-mode input voltage increases. A similar effect happens when there is no DC current path between INN, INP, and HGND. If the input common-mode voltage exceeds the common-mode overvoltage detection threshold VCMov, the device provides a constant bitstream of logic 1's at the output, as shown in Figure 7-7; that is, DOUT is permanently high. A zero is not generated every 128 clock pulses, which differentiates this condition from a valid positive full-scale input. This feature is useful to identify interconnect problems on the board.
Figure 7-6 Output of the AMC1306M25E in Case of a Common-Mode OvervoltageThere is no common-mode overvoltage detection in the negative direction; thus, if the common-mode input voltage is below the minimum VCM value specified in the Recommended Operating ConditionsRecommended Operating ConditionsRecommended Operating Conditions table, the bitstream at the DOUT output is not determined.
