6.4 Device Functional Modes

The AMC0106M25 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 推奨動作条件 but 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.
  • Common-mode input violation: AVDD and DVDD are supplied within the respective recommended operating conditions. However, the common-mode input voltage VCM = (VINP + VINN) / 2 is outside the recommended operating conditions. The device outputs invalid data, independent of the differential input voltage VIN.
  • Differential input voltage range violation (full-scale input): VAVDD, VDVDD, and VCM are within the recommended operating conditions. However, the differential input voltage VIN = (VINP – VINN) 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, VCM, and VIN are within the recommended operating conditions. The device outputs a digital bitstream as explained in the Digital Output section.
