Instructions
Power Supply:
- Connect the VCC pin to a stable 4.5V to 5.5V power supply.
- Connect the GND pin to the ground.
Reference Voltage:
- Connect the VREF pin to an external reference voltage source within the range of 2.5V to 5.5V.
SPI Interface:
- Connect the SCLK (Serial Clock) pin to the clock signal from the microcontroller.
- Connect the SDI (Serial Data In) pin to the data output of the microcontroller.
- Connect the CS (Chip Select) pin to the chip select signal from the microcontroller.
Output Configuration:
- The DAC outputs (OUTA and OUTB) can be connected to the load or further buffering stages as required.
Initialization:
- Ensure that the CS pin is held high when not in use to keep the device in a high-impedance state.
- To write to the DAC, bring the CS pin low, send the appropriate command and data via the SPI interface, and then bring the CS pin high again.
Shutdown Mode:
- To enter shutdown mode, set the appropriate bit in the control register to reduce power consumption to 1 μA.
Calibration:
- For optimal performance, calibrate the DAC using the provided calibration registers to correct for any non-linearity errors.
Handling:
- Handle the device with care to avoid static damage. Use proper ESD protection when handling the component.
Storage:
- Store the device in a dry, cool place to prevent moisture damage. Follow the storage recommendations provided by the manufacturer.
