The maximum output current of the DAC908U/1K is 5mA. This is not explicitly stated in the datasheet, but it can be inferred from the output impedance and voltage range specifications.
To ensure monotonicity of the DAC908U/1K, it is recommended to use a clock frequency of at least 10 times the update rate, and to avoid sudden changes in the input code. Additionally, the DAC908U/1K has a built-in monotonicity feature that can be enabled by setting the appropriate register bits.
The settling time of the DAC908U/1K is typically around 2-3 microseconds, but this can vary depending on the output load and the specific application. It is recommended to consult the datasheet and application notes for more detailed information.
Yes, the DAC908U/1K can be used with a single supply voltage, but it requires an external voltage reference. The device can operate from a single supply voltage of 2.7V to 5.5V, and the output voltage range can be adjusted using the internal voltage reference or an external voltage reference.
The DAC908U/1K can be interfaced with a microcontroller using a serial interface such as SPI or I2C. The device has a 16-bit or 24-bit parallel input interface, and the microcontroller can write data to the DAC using a serial-to-parallel converter or a dedicated DAC interface.
