Instructions for Use

1. Power Supply:

   • Connect the VCC pin to the supply voltage (2.7 V to 5.5 V).
   • Connect the GND pin to the ground.

2. I2C Communication:

   • Connect the SDA (Data) and SCL (Clock) pins to the corresponding I2C lines on your microcontroller.
   • Ensure pull-up resistors are used on the SDA and SCL lines if not already provided by the microcontroller.

3. Initialization:

   • Send the initialization command to the device to set it to the default state.
   • The default address is typically 0x2E, but this can be configured using the A0, A1, and A2 pins.

4. Reading and Writing:

   • Use I2C commands to read the current position or write a new position to the wiper.
   • The wiper position can be set from 0 to 255 (8-bit resolution).

5. Non-Volatile Memory:

   • To store the current wiper position in EEPROM, send the appropriate command.
   • This ensures the position is retained even when power is removed.

6. Temperature Considerations:

   • Ensure the device operates within the specified temperature range (-40°C to +85°C) to avoid damage or incorrect operation.

7. Power Dissipation:

   • Do not exceed the maximum power dissipation of 100 mW to prevent overheating and potential damage to the device.

8. Handling:

   • Handle the device with care to avoid static discharge, which can damage the sensitive components.
   • Follow standard ESD (Electrostatic Discharge) precautions during handling and assembly.
