The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents potential latch-up conditions.
To ensure accurate voltage output, it's essential to use a high-precision voltage reference, such as the REF5025, and to follow proper PCB layout and grounding techniques to minimize noise and interference.
The maximum output current capability of the DAC7631E/1K is 5 mA. Exceeding this limit can cause damage to the device or affect its accuracy.
Yes, the DAC7631E/1K can be used in a ratiometric configuration, where the output voltage is proportional to the reference voltage. This can be useful in applications where the output voltage needs to track changes in the reference voltage.
During power-down or reset, it's recommended to hold the digital inputs in a static state (either high or low) to prevent unwanted output voltage transitions. This can be achieved using pull-up or pull-down resistors or by using a digital buffer with a fixed output state.
