Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the range of 4.75V to 5.25V for optimal performance.

2. Analog Input:

   • The analog input voltage should be between 0V and the reference voltage (VREF).

3. Reference Voltage:

   • The internal reference voltage is set at 2.5V, which can be used directly or an external reference can be applied if needed.

4. Conversion Process:

   • The conversion time is typically 13 microseconds. Ensure that your system timing accounts for this delay.

5. Power Management:

   • With all channels active, the device consumes approximately 15mA. Manage power settings based on channel usage to optimize power consumption.

6. Linearity:

   • The device maintains differential nonlinearity (DNL) within 卤1 LSB and integral nonlinearity (INL) within 卤2 LSB, ensuring accurate conversions.

7. Signal Quality:

   • A signal-to-noise ratio (SNR) of 90dB provides high-quality signal processing.

8. Channel Sequencing:

   • Utilize the built-in channel sequencer to manage multiple analog inputs efficiently.

9. Interface:

   • Communicate with the device using the SPI interface for configuration and data retrieval.
