10-bit current-source DAC with 35 ns settling
The THS5651AIPW is a 10-bit current-output DAC from Texas Instruments' CommsDAC series, built on a current-source architecture with differential output and a parallel data interface. Its 35 ns typical settling time suits high-speed waveform generation — think arbitrary function generators, baseband I/Q modulation, or pin-level signal reconstruction where the DAC's update rate must keep pace with the downstream analog path.
Linearity and supply rails
INL is ±0.5 LSB and DNL is ±0.25 LSB, both typ — this level of differential linearity means the DAC stays monotonic across the full 10-bit range, critical in control loops where a non-monotonic step would reverse the output direction.
Package and reference options
Reference type is selectable between external and internal, giving the designer control over the full-scale current: an external reference sets the output range independently of the supply, while the internal reference simplifies a single-supply bill of materials.
