7.5 Device Functional Modes

The AMC0x11S operates in one of the following states:

  • OFF-state: The low-side supply (VDD2) is below the VDD2UV threshold. The device is not responsive. OUT is in Hi-Z state. Internally, OUT is clamped to VDD2 and GND2 by ESD protection diodes.
  • Missing high-side supply: The low-side of the device (VDD2) is supplied and within the Recommended Operating Conditions section. The high-side supply (VDD1) is below the VDD1UV threshold. The OUT pin is driven to VREFIN (0V if REFIN is shorted to GND2).
  • Analog input overrange (positive full-scale input): VDD1 and VDD2 are within recommended operating conditions but the analog input voltage VIN is above the maximum clipping voltage VClipping, MAX. The device outputs VClipping + VREFIN at the OUT pin.
  • Analog input underrange (negative full-scale input): VDD1 and VDD2 are within recommended operating conditions but the analog input voltage VIN is below the minimum clipping voltage VClipping, MIN. The OUT pin is driven to VREFIN (0V if REFIN is shorted to GND2).
  • Normal operation: VDD1, VDD2, and VIN are within the recommended operating conditions. The device outputs a voltage proportional to the input voltage.

Table 7-1 lists the operating modes.
