16-bit dual-channel DAC with 10.4 ns settling
The DAC5687IPZP from Texas Instruments is a 16-bit dual digital-to-analog converter with a current-sink architecture and unbuffered current output, delivering a typical settling time of 10.4 ns. That settling speed makes it suitable for high-speed waveform generation in communications or test equipment where the output must slew between levels within a single clock cycle. It provides differential output, which means the signal is delivered as a pair of complementary currents — this common-mode rejection helps suppress noise pick-up on the board trace between the DAC and the following amplifier or filter stage.
Package and supply rails for the board designer
It runs on dual supply rails: analog 3V to 3.6V and digital 1.71V to 2.15V. The separate domains mean the digital interface can operate from a lower-voltage logic rail while the analog core gets the headroom it needs for full-scale output swing. The data interface is parallel — 16 data lines plus control signals — so the layout must route a 16-bit bus with matched trace lengths to keep skew below the setup/hold window of the DAC.
