The R-2R architecture delivers a buffered voltage output with a settling time of 10 µs, suitable for multi-channel industrial control loops, programmable voltage references, and automated test equipment where board space is tight and channel count drives the BOM. ## Supply rails and temperature range Analog section runs on ±5 V, the digital core on a separate 5 V supply. That split-rail requirement is the main PSU constraint — the analog rail needs a bipolar supply, so a single +5 V rail won't cut it. The -40°C to 85°C operating range covers factory-floor cabinets, outdoor telecom shelters, and engine-bay-adjacent enclosures without stepping up to a military-grade part. ## Linearity and interface INL is ±2 LSB, DNL ±1 LSB — typical for a 16-bit R-2R DAC and sufficient for most closed-loop analog outputs without external calibration. The SPI interface uses an external reference, so the reference voltage directly sets the output span; pick a low-drift reference if the application demands better than 16-bit accuracy over temperature. ## Active and available Lifecycle status is Active and ROHS3 compliant. No end-of-life notice or last-time-buy window on this line. For a precision quad DAC in a 48-SSOP footprint, it's a current-production part that can be specified into new designs without obsolescence risk.","metaTitle":"DAC7634EB 16-bit Quad DAC, SPI, Voltage Output, 48-SSOP","metaDescription":"TI DAC7634EB 16-bit quad voltage-output DAC with SPI interface, 10 µs settling time, ±2 LSB INL, industrial temp range -40°C to 85°C.

The DAC7750IPWP is a different device — it is a single-channel 12-bit current-output DAC with a wider temperature range and internal reference, not a functional replacement for the quad 16-bit voltage-output DAC7634EB."},{"question":"How to interface DAC7634EB with SPI?","answer":"The DAC7634EB uses a standard SPI data interface with an external reference. The digital supply is 5 V, so the SPI signals must be 5 V-compatible. For 3.3 V logic, a level shifter is required between the host controller and the DAC's digital inputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DAC7634EB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DAC7634EB when reusing this data.
