Instructions for Use:
Power Supply:
- Ensure the supply voltage (VDD) is within the range of 2.7V to 5.5V.
Reference Voltage Setup:
- Connect an external reference voltage (VREF) between 0V and 5V to achieve the desired output voltage range.
Digital Input Configuration:
- Apply digital input signals within the range of 0V to VDD. The DAC7811 supports a parallel interface for data entry.
Output Configuration:
- The output voltage (VOUT) can be adjusted by configuring the resistor (RSET). For optimal performance, use a 50kΩ resistor with a 2.5V reference voltage.
Timing Considerations:
- Account for the output settling time of 8μs when designing circuits that require rapid changes in output voltage.
Linearity Calibration:
- Check and calibrate for Integral Nonlinearity (INL) and Differential Nonlinearity (DNL) errors as specified to ensure accurate analog output.
Power Management:
- Be mindful of power dissipation, especially at full-scale output, to avoid overheating. The device dissipates up to 30mW at VDD = 5V.
Installation and Handling:
- Handle the DAC7811 with care to avoid ESD damage. Follow standard procedures for surface-mount devices during installation.
