Instructions for Use
Power Supply:
- Connect the supply voltage (VCC) within the range of 2.7V to 5.5V.
- Ensure a stable power supply to avoid fluctuations that could affect the performance of the DAC.
Reference Voltage:
- The internal reference voltage is 2.048V. If an external reference is used, ensure it is within the specified range and stable.
Output Configuration:
- The output voltage (VOUT) can be set relative to the reference voltage (VREF).
- The output range is from -0.1V to VCC + 0.1V.
DNL and INL:
- The differential nonlinearity (DNL) and integral nonlinearity (INL) are specified to ensure accurate conversion.
- These parameters should be within ±1 LSB for optimal performance.
Settling Time:
- The output settling time is typically 30 μs for a 10-bit resolution to within 0.1% of the final value.
- Ensure that the system allows sufficient time for the output to settle before reading or using the value.
Power Consumption:
- The typical power consumption is 1.2 mA when all outputs are at mid-scale.
- Ensure the power supply can handle the current requirements.
Output Current:
- Each output channel can source or sink up to 10 mA.
- Avoid exceeding this limit to prevent damage to the device.
General Handling:
- Handle the device with care to avoid static discharge which can damage the sensitive components.
- Follow proper PCB layout guidelines to minimize noise and interference.
Programming:
- Refer to the datasheet for specific programming instructions and communication protocols (e.g., SPI, I2C).
- Ensure the correct configuration of control pins and registers for desired operation.
For detailed information and specific applications, refer to the full datasheet provided by the manufacturer.
