Instructions for Use:

1. Power Supply:

   • Connect the supply voltage (VDD) between 4.5V and 5.25V.
   • Ensure the supply current does not exceed 10mA when all channels are active.

2. Analog Input:

   • The analog input voltage (VIN) should be within the range of 0V to VDD relative to ground.

3. Conversion:

   • The conversion time for an 8-bit conversion is typically 7 渭s.
   • The ADC has a resolution of 8 bits.

4. Linearity:

   • Ensure that the differential nonlinearity (DNL) is within 卤1 LSB and the integral nonlinearity (INL) is within 卤1 LSB to maintain accurate conversions.

5. Error Correction:

   • The offset error is typically 2 mV, and the gain error is 0.2%. These values can be used to calibrate the ADC if necessary.

6. Power-down Mode:

   • When all channels are powered down, the current consumption (IDD(PD)) should be less than 1 渭A.

7. Temperature Range:

   • The device operates reliably over a temperature range from -40掳C to 85掳C.

8. Handling:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).

9. Application Notes:

   • Refer to the datasheet for detailed application notes and circuit diagrams to ensure optimal performance.
