4 ADS7142-Q1 GUI Functional Modes

The ADS7142-Q1 device has the following functional modes:

  • Manual Mode: In this mode, the host provides I2C frames to control conversion and read data after each conversion.
  • Autonomous Mode: The device features an internal data buffer that can store the conversion results of the ADC in Autonomous Mode without the host controlling the conversion.
  • High Precision Mode: In High Precision Mode, the results stored in the internal data buffer are accumulated to increase the precision of the conversion results.

The device powers up in Manual Mode and can be configured into any of the functional modes by writing the configuration registers for the desired mode.
