6.4 Device Functional Modes

The AMC0136 operates in one of the following states:

  • OFF-state: The low-side of the device (AVDD) is not supplied. The device is not responsive and DOUT is in high-impedance state. Internally, DOUT is clamped to DVDD and DGND by ESD protection diodes.
  • Missing high-side supply: DVDD is supplied within the Recommended Operating Conditions. VAVDD is below the AVDDUV threshold. The device outputs a constant bitstream of logic 0's, as described in the Output Behavior in Case of a Missing High-Side Supply section.
  • Input voltage range violation (full-scale input): VAVDD and VDVDD are supplied within the respective recommended operating conditions but the input voltage VIN exceeds the clipping voltage (|VIN| > |VClipping|). The device outputs a fixed pattern, as described in the Output Behavior in Case of a Missing High-Side Supply 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.
