The recommended power-up sequence is to apply VDD first, followed by AVDD, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly and the device operates as expected.
To ensure accurate output voltage levels, it is essential to use a high-quality external voltage reference, such as the REF5025, and to follow proper PCB layout and design guidelines to minimize noise and interference.
The maximum output current capability of the DAC2902Y/250G4 is 10 mA per channel. Exceeding this limit can cause damage to the device or affect its performance.
To implement a bipolar output voltage range, you can use an external amplifier, such as the OPA2822, to invert and scale the output voltage. Alternatively, you can use a voltage translator, such as the TXB0104, to level-shift the output voltage.
The recommended clock frequency range for the DAC2902Y/250G4 is 10 MHz to 100 MHz. Operating the device outside this range may affect its performance or cause errors.
