Product details

It settles in 10.4 ns typical. The output is current-unbuffered and requires an external transimpedance amplifier or resistor to convert to a voltage. That gives the designer control over the output compliance range and noise floor, but adds a few external components. The reference can be internal or external, so you can share a precision reference across multiple DACs on the same board. Supply rails are split: analog at 3 V to 3.6 V, digital at 1.7 V to 1.9 V.

Industrial temperature range and package

It is not qualified for automotive under-hood environments (no AEC-Q100 in the record).

For a BOM freeze or a new design, this part carries no imminent obsolescence risk.
