Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 4.5V to 5.5V.
   • Connect a decoupling capacitor (e.g., 0.1μF) close to the power pins to filter noise.

2. Input Signal:

   • The differential input voltage should be within the range of -0.3V to V_CC + 0.3V.
   • For optimal performance, ensure the input signal is stable and within the specified range.

3. Output Configuration:

   • The output voltage swing is from V_CC - 1.5V to V_CC - 0.5V.
   • Use appropriate pull-up or pull-down resistors if necessary to ensure proper logic levels.

4. Conversion Process:

   • The typical conversion time for an 8-bit conversion is 11μs, with a maximum of 15μs.
   • Ensure the clock frequency (f_S) is set appropriately to avoid exceeding the conversion time.

5. Power Consumption:

   • The device typically consumes 3.5mA when operating at a sampling frequency of 10kHz.
   • Consider this in your power budget and thermal design.

6. Capacitance Considerations:

   • The input capacitance is 20pF, and the output capacitance is 10pF.
   • These values can affect the signal integrity and should be considered in high-frequency applications.

7. Linearity:

   • The differential nonlinearity (DNL) and integral nonlinearity (INL) are both within ±1LSB, ensuring good linearity and accuracy.

8. Handling and Storage:

   • Handle the device with care to avoid electrostatic discharge (ESD).
   • Store in a dry environment to prevent moisture damage.

9. Testing and Verification:

   • Before finalizing the design, test the device under various conditions to ensure it meets the required specifications.
   • Use a digital multimeter or oscilloscope to verify the output signals and conversion times.
