The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital inputs. This ensures that the internal circuitry is properly biased and configured before the digital inputs are applied.
To ensure accurate voltage output, it is essential to use a high-precision voltage reference (VREF) and to minimize noise on the VREF pin. Additionally, the output voltage should be buffered with an op-amp to prevent loading effects.
The maximum output current of the DAC7613E/1K is 5mA. Exceeding this current limit can cause damage to the device or affect its accuracy.
To minimize output glitches during power-up or code changes, it is recommended to use a glitch filter or a deglitch circuit at the output of the DAC. This can be implemented using an RC filter or a dedicated glitch filter IC.
The DAC7613E/1K's performance is affected by temperature, with changes in temperature causing changes in the output voltage. To minimize temperature-related errors, it is recommended to use a temperature-compensated voltage reference and to keep the device within its specified operating temperature range.
