6.3.3 Analog Output
The AMC3330-Q1 offers a differential analog output comprised of the OUTP and OUTN pins. For differential input voltages (VINP – VINN) in the range from –1 V to 1 V, the device provides a linear response with a nominal gain of 2. For example, for a differential input voltage of 1 V, the differential output voltage (VOUTP – VOUTN) is 2 V. At zero input (INP shorted to INN), both pins output the same voltage, VCMout, as specified in the Electrical Characteristics table. For absolute differential input voltages greater than 1.0 V but less than 1.25 V, the differential output voltage continues to increase in magnitude but with reduced linearity performance. The outputs saturate as shown in Figure 6-3 if the differential input voltage exceeds the VClipping value.
Figure 6-3 AMC3330-Q1 Output BehaviorThe AMC3330-Q1 provides a fail-safe output that simplifies diagnostics on system level. The fail-safe output is active when the integrated DC/DC converter or hgh-side LDO don't deliver the required supply voltage for the high-side of the device. Figure 6-4 and Figure 6-5 illustrate the fail-safe output of the AMC3330-Q1 that is a negative differential output voltage value that does not occur under normal operating conditions. Use the maximum VFAILSAFE voltage specified in the Electrical Characteristics table as a reference value for the fail-safe detection on system level.
