The AD9704BCPZRL7 is an 8-bit current-output DAC from the TxDAC® family, built on a current-source architecture with a typical settling time of 11 ns — fast enough for waveform generation in arbitrary-function generators, direct-digital synthesis (DDS) front-ends, and high-speed instrumentation where the update rate is limited by the DAC's settling, not the digital interface. Its INL and DNL are specified at ±0.03 LSB and ±0.02 LSB respectively — these are the static linearity figures that determine how accurately the output current tracks the digital code. For a communications or test-equipment design, the DNL figure matters most: a ±0.02 LSB DNL means no missing codes at 8-bit resolution, and the output glitch energy stays low enough that post-filtering is straightforward. The part operates from dual supply rails — 1.8 V for the digital core and 3.3 V for the analog output stage — which is the standard split-rail arrangement for high-speed DACs that interface with 1.8 V logic while delivering a 0 to 20 mA (typical) output swing into a resistive load.
Package and board-fit: 32-LFCSP (5x5 mm)
The exposed paddle must be soldered to a thermal land on the board — the datasheet's recommended footprint includes a 3.5x3.5 mm pad with via array to the ground plane for heat sinking.
