Frequently Asked Questions
What are the DAC conversion bit depths available?
The devices offer interchangeable 14-bit and 16-bit performance parts that utilize parallel input technology.
How is glitch energy handled by these DACs?
They include an internal deglitcher circuit designed to reduce the glitch impulse to less than $2 ext{nV-s}$ (typ).
What are the methods for resetting the device scale?
The asynchronous CLR pin can reset the chip to zero scale, and Power-On Reset (POR) resets it to midscale.
What kind of output signal do these parts provide?
They are multiplying current output DACs that allow for 4-quadrant multiplication in unipolar or bipolar modes.
