6.4 Device Functional Modes

The AMC0386-Q1 operates in one of the following states:

  • OFF-state: The low-side of the device (AVDD) is below the AVDDUV threshold. The device is not responsive. OUT is Hi-Z state. Internally, OUT and CLKIN are clamped to DVDD and DGND by ESD protection diodes.
  • Missing high-side supply: The low-side of the device (DVDD) is supplied and within Recommended Operating Conditions. The high-side supply (AVDD) is below the AVDDUV threshold. The device outputs a constant bitstream of logic 0's, as described in the section.
  • Analog input overrange (positive fullscale input): AVDD and DVDD are within recommended operating conditions but the analog input voltage VIN = (VSNSP– VSNSN) is above the maximum clipping voltage (VClipping, MAX). The device outputs a logic 0 every 128 clock cycles, as described in the Output Behavior in Case of a Fullscale Input section.
  • Analog input underrange (negative fullscale input): AVDD and DVDD are within recommended operating conditions but the analog input voltage VIN = (VSNSP– VSNSN) is below the minimum clipping voltage (VClipping, MIN). The device outputs a logic 1 every 128 clock cycles, as described in the Output Behavior in Case of a Fullscale Input section.
  • Normal operation: VAVDD, VDVDD, and VIN are within the recommended operating conditions. The device outputs a digital bitstream, as explained in the Digital Output section.

Table 6-1 lists the operational modes.
