8.4.1 Fail-Safe Output
In the case of a missing AVDD high-side supply voltage, the output of the ΔΣ modulator is not defined and can cause a system malfunction. In systems with high safety requirements, this behavior is not acceptable. Therefore, as shown in Figure 47, the AMC1106 implements a fail-safe output function that ensures that the DOUT output of the device offers a steady-state bitstream of logic 0's in case of a missing AVDD.
Similarly, as also shown in Figure 47, if the common-mode voltage of the input reaches or exceeds the specified common-mode overvoltage detection level VCMov as defined in the Electrical Characteristics table, the AMC1106 generates a steady-state bitstream of logic 1's at the DOUT output.
