Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (V_DD) is within the range of 2.7 V to 3.6 V.
   • Connect the ground (GND) pin to a stable reference ground.

2. Analog Input:

   • The analog input voltage (V_IN) should be between 0 V and V_DD.
   • Avoid exceeding the input voltage range to prevent damage to the device.

3. Digital Output:

   • The digital output logic levels are defined by V_OH and V_OL. Ensure the load current (I_O) does not exceed the specified limits.
   • Connect the digital outputs to the appropriate logic inputs of your system.

4. Conversion Time:

   • The conversion time (t_C) is typically 1 μs. Ensure that the system allows sufficient time for the ADC to complete a conversion before reading the result.

5. Power Consumption:

   • The average power consumption (P_AVG) is typically 1.2 mW. This value can help in thermal management and power budgeting.

6. Temperature Range:

   • The device is designed to operate within a temperature range of -40°C to 85°C. Ensure the operating environment stays within this range to maintain performance and reliability.

7. Resolution:

   • The ADC has a resolution of 10 bits, providing 1024 possible output codes.

8. Linearity:

   • The differential nonlinearity (DNL) and integral nonlinearity (INL) are specified to ensure accurate conversions. DNL should be within ±0.5 LSB and INL within ±1.0 LSB.

9. Signal-to-Noise Ratio (SNR):

   • The SNR is typically 60 dB, indicating the ratio of the signal level to the noise level in the system.

10. Handling and Storage:

    • Handle the device with care to avoid static discharge and physical damage.
    • Store the device in a dry, cool place away from direct sunlight and extreme temperatures.
