8.4.1 Fail-Safe Output
In the case of a missing high-side supply voltage AVDD, the output of a ΔΣ modulator is not defined and can cause a system malfunction. In systems with high safety requirements, this behavior is not acceptable. Therefore, the AMC1306 implements a fail-safe output function that ensures that the output DOUT of the device offers a steady-state bitstream of logic 0's in case of a missing AVDD, as shown in Figure 53.
Additionally, 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 AMC1306 offers a steady-state bitstream of logic 1's at the output DOUT, as also shown in Figure 53.
