PRODUCTION DATA
The AMC1350-Q1 offers a differential analog output on the OUTP and OUTN pins. For differential input voltages (VINP – VINN) in the range from –5 V to +5 V, the device provides a linear response with a nominal gain of 0.4 V/V. For example, for a differential input voltage of 5 V, the differential output voltage (VOUTP – VOUTN) is 2 V. At zero input (INP shorted to INN), both pins output the same common-mode output voltage VCMout, as specified in the Section 6.9 table. For absolute differential input voltages greater than 5 V but less than 5.75 V, the differential output voltage continues to increase in magnitude but with reduced linearity performance. The outputs saturate at a differential output voltage of VCLIPout, as shown in Figure 7-2, if the differential input voltage exceeds the VClipping value.
The AMC1350-Q1 output offers a fail-safe feature that simplifies diagnostics on a system level. Figure 7-2 shows the fail-safe condition, in which the AMC1350-Q1 outputs a negative differential output voltage that does not occur under normal operating conditions. The fail-safe output is active in two cases:
Use the maximum VFail-safe voltage specified in the Section 6.9 table as a reference value for fail-safe detection on a system level.
