It delivers ±0.5 LSB INL and ±0.5 LSB DNL, settling to 1 LSB within 1 µs typical. The SPI data interface accepts update commands at clock rates limited only by the host controller. An external voltage reference sets the full-scale output range, giving the designer control over the span independent of the supply rails. Supply range is 2.7 V to 5.5 V for both analog and digital sections, simplifying single-rail designs. The part is packaged in an 8-lead WFDFN with exposed pad (3 mm × 3 mm) for surface-mount assembly. ## What the ±0.5 LSB linearity means for your BOM The ±0.5 LSB INL and DNL guarantee monotonic behavior across the full 16-bit code range. No missing codes, no non-monotonic steps. That matters when the DAC is driving a closed-loop actuator or setting a precision threshold — the output voltage moves predictably with each code increment. The 1 µs settling time supports update rates up to roughly 1 Msps in a sample-and-hold application, though the SPI bus speed and host overhead will be the real limit. For a BOM line that needs a clean 16-bit voltage output without external buffer or level shift, this part covers the analog path from the serial interface to the output pin. ## Commercial temperature grade — design-in boundary The operating temperature range is 0°C to 70°C. The AD5541ARZ peer is rated from -40°C to 125°C. ## Lifecycle and supply position Status is Active per the manufacturer, with ROHS3 compliance. For dual-sourcing consideration, the AD5541ARZ is a functional equivalent with the same R-2R core, 16-bit resolution, ±0.5 LSB linearity, and 1 µs settling, but in an SOIC-8 package and rated for -40°C to 125°C.","metaTitle":"LTC2641CDD-16#PBF 16-Bit DAC, SPI, 1µs, 8-DFN","metaDescription":"Linear Technology LTC2641CDD-16#PBF 16-bit voltage-output DAC, R-2R architecture, ±0.5 LSB INL/DNL, 1µs settling, SPI interface, 8-DFN package.
