The AD5676ARUZ-REEL7 is an Analog Devices nanoDAC+® 16-bit, 8-channel voltage-output digital-to-analog converter in a 20-TSSOP package. It integrates eight independent buffered DACs with a string architecture, settling to 0.1% in 8µs. The SPI/DSP serial interface handles daisy-chaining for systems needing more than eight channels. With separate analog supply (2.7V to 5.5V) and digital supply (1.8V to 5.5V), it fits mixed-voltage designs — 3.3V analog with 1.8V logic, or 5V industrial rails.
External reference — plan your BOM accordingly
This DAC requires an external voltage reference (the Reference Type is External). That means the BOM needs a precision reference IC — such as the ADR4525 or ADR4530 — and its associated bypass caps. The benefit is flexibility: you choose the reference voltage that sets the full-scale output range, and the reference's noise/drift performance directly sets the system's accuracy floor. If you prefer an integrated reference, the pin-compatible AD5676RBRUZ includes a 2.5V internal reference, though it trades off the ability to select a different reference voltage.
For new designs or ongoing production, this part can be specified without obsolescence concern. Both are ROHS3 compliant.
For a BOM line requiring this exact 8-channel, 16-bit DAC in the 20-TSSOP package, the AD5676ARUZ-REEL7 is a clean fit with no single-source risk — the part is widely distributed and the active status means factory lead times are predictable.
