Instructions for ADC124S021CIMM

1. Power Supply:

   • Connect the supply voltage (VDD) to a stable power source between 2.7V and 5.5V.
   • Ensure that the ground (GND) is properly connected.

2. Analog Input:

   • Apply the analog signal to the analog input pin (VIN). The voltage should be within the range of 0V to VDD.

3. Digital Output Configuration:

   • Configure the digital output levels according to the supply voltage. Ensure the high level does not exceed VDD-0.3V and the low level does not exceed 0.3V.

4. Sampling:

   • Set the sampling rate up to 200 kSPS as required by your application.

5. Power Management:

   • For active mode, ensure the power consumption does not exceed 1.9mA.
   • To enter shutdown mode, set the appropriate control signal which reduces power consumption to approximately 1μA.

6. Linearity:

   • Verify that the differential nonlinearity (DNL) and integral nonlinearity (INL) are within ±1 LSB for accurate conversions.

7. Signal Quality:

   • Monitor the signal-to-noise ratio (SNR), which typically operates around 84 dB for optimal performance.

8. Initialization:

   • Before starting conversion, initialize the device by setting up the necessary configuration registers via the SPI interface.

9. Data Conversion:

   • Trigger the conversion process either through software command or hardware signal as specified in the datasheet.

10. Reading Data:

    • After conversion, read the data from the digital output pins using the SPI interface.

Ensure all connections are secure and follow the manufacturer’s guidelines for optimal performance.
