6.4 Device Functional Modes

The AMC0100R 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 recommended operating conditions. The high-side supply (VDD1) is below the VDD1UV threshold. The OUT pin is driven to VREFIN / 2.
  • 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 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 GND2.
  • Normal operation: VDD1, VDD2, and VIN are within the recommended operating conditions. The device outputs a voltage that is proportional to the input voltage.

Table 6-1 lists the operating modes.
