SBAS895D May 2018 – May 2022 AMC1300
PRODUCTION DATA
The AMC1300 offers a differential analog output comprised of the OUTP and OUTN pins. For differential input voltages (VINP – VINN) in the range from –250 mV to +250 mV, the device provides a linear response with a nominal gain of 8.2. For example, for a differential input voltage of 250 mV, the differential output voltage (VOUTP – VOUTN) is 2.05 V. At zero input (INP shorted to INN), both pins output the same common-mode output voltage VCMout, as specified in the Section 7.9 table. For absolute differential input voltages greater than 250 mV but less than 320 mV, 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 8-2, if the differential input voltage exceeds the VClipping value.
The AMC1300 offers a fail-safe feature that simplifies diagnostics on system level. Figure 8-2 shows the fail-safe potential that is 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 VFAILSAFE voltage specified in the Section 7.9 table as a reference value for fail-safe detection on system level.
