Instructions for ADC121S051CIMFX/NOPB

1. Powering the Device:

   • Ensure that the supply voltage (VDD) is within the range of 2.7V to 5.5V.
   • Connect VDD to the power supply and GND to the ground.

2. Connecting the Analog Input:

   • Connect the analog signal to be measured to the VIN pin.
   • The input voltage should not exceed the supply voltage (VDD).

3. Configuring the ADC:

   • Use the configuration register to set up the ADC according to your requirements, such as setting the operating mode or initiating a conversion.
   • Refer to the device datasheet for specific register settings.

4. Starting a Conversion:

   • Initiate a conversion by writing to the appropriate register or toggling the start conversion pin.
   • Wait for the conversion time (approximately 183 μs).

5. Reading the Result:

   • After the conversion is complete, read the result from the output data register.
   • The result will be a 12-bit digital value representing the analog input voltage.

6. Entering Shutdown Mode:

   • To reduce power consumption, enter the shutdown mode by configuring the appropriate register bit.
   • In this mode, the current consumption drops to approximately 0.5 μA.

7. Returning to Normal Operation:

   • To resume normal operation from shutdown mode, clear the shutdown bit in the configuration register.
