Frequently Asked Questions
How does this DAC maintain high performance and throughput?
It uses double-buffered input registers, allowing it to appear as a two-byte “stack” for maximum throughput.
Is this DAC compatible with 8-bit data interfaces?
Yes, the DAC1230 series is pin compatible with the DAC0830 and can be used directly on an 8-bit data bus internally serializing the data.
What voltage range should I use for a single power supply?
The device operates using a single DC power supply ranging from 5 V to 15 V.
What alternatives are available if I need a different resolution?
For lower resolutions, the DAC1000 series is available for 10-bit, and the DAC0830 series is an alternative for 8-bit.
