7.4.1 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 verifies that the output DOUT of the device offers a steady-state bitstream of logic 0s in case of a missing AVDD, as shown in Figure 7-7.

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 1s at the output DOUT, as also shown in Figure 7-7.
