The R-2R architecture gives monotonic performance — the output moves in one direction as the code increases, which matters when the DAC is driving a closed-loop system like a servo valve or a programmable power supply where a non-monotonic step could cause oscillation. Settling to within 1 LSB takes 10 µs typical, so the update rate per channel is roughly 100 kSPS. The SPI interface keeps the pin count low — three wires (SCLK, DIN, CS) plus a shared load-dac strobe handle all four channels. ## Accuracy and reference: what the INL/DNL numbers mean Integral non-linearity is ±3 LSB maximum, differential non-linearity ±2 LSB maximum. At 16 bits, 1 LSB is 15.26 ppm of full scale. ±3 LSB INL means the worst-case deviation from a straight line is about 46 ppm of full scale — that is the accuracy floor for the transfer function. For a calibration technician, this sets the limit on how tight the system can be trimmed without a lookup table. The reference is external, so the absolute accuracy of the output depends entirely on the voltage reference you supply. A 2.5 V reference with ±0.05% initial accuracy and 5 ppm/°C drift will dominate the error budget, not the DAC itself. The analog supply rails are ±5 V, giving a bipolar output range up to ±Vref — useful for industrial signal chains that need to swing through zero. ## Package, temperature grade, and board integration The 48-BSSOP body is 7.50 mm wide, 0.295-inch pitch — a standard SSOP footprint. The surface-mount package is suited for reflow assembly; the Tube shipping format means the parts arrive in anti-static tubes, not tape-and-reel, so plan for pick-and-place feeder changeover if your line is set up for reels.","metaTitle":"Texas Instruments DAC7634E 16-bit Quad DAC, 48-SSOP, Active","metaDescription":"Texas Instruments DAC7634E 16-bit quad voltage-output DAC, 10 µs settling, SPI, ±5V analog supply, industrial temp -40°C to 85°C, 48-SSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Output Type":"Voltage - Buffered","Architecture":"R-2R","INL/DNL (LSB)":"±3, ±2","Mounting Type":"Surface Mount","Settling Time":"10µs","Data Interface":"SPI","Number of Bits":"16","Package / Case":"48-BSSOP (0.295\\\", 7.50mm Width)","Reference Type":"External","lifecycle_stage":"eol_hot","Differential Output":"No","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"48-SSOP","Number of D/A Converters":"4","Voltage - Supply, Analog":"±5V","Voltage - Supply, Digital":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$50.43","priceTiers":[{"qty":1,"price":"$50.43000","currency":"USD"},{"qty":10,"price":"$47.04500","currency":"USD"},{"qty":25,"price":"$45.07280","currency":"USD"},{"qty":100,"price":"$40.84730","currency":"USD"},{"qty":250,"price":"$39.86400","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DAC7634E/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DAC7634E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DAC7634E when reusing this data.
