That is 16 separate analog outputs you can update independently over a single SPI bus — no external muxing or sample-and-hold needed. The multiplying DAC architecture means the output is the product of the digital code and an external reference voltage, so you can scale the full-scale range dynamically by changing the reference. This is useful in programmable power supplies, automated test equipment, or any system where one DAC channel per control loop is the rule. ## Accuracy and settling — the specs that matter for closed-loop control Integral nonlinearity is ±3 LSB maximum, differential nonlinearity ±1 LSB maximum. That ±1 LSB DNL guarantees monotonicity — every code step produces a positive voltage increment.","metaTitle":"LTC2688HUJ-16#PBF 16-Channel 16-Bit DAC, Multiplying, SPI","metaDescription":"Analog Devices LTC2688HUJ-16#PBF is a 16-channel, 16-bit multiplying DAC with buffered voltage output, SPI interface, ±3 LSB INL, -40°C to 125°C range.","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":"Multiplying DAC","INL/DNL (LSB)":"±3LSB (Max), ±1 (Max)","Mounting Type":"Surface Mount","Settling Time":"28µs","Data Interface":"SPI","Number of Bits":"16","Package / Case":"40-WFQFN Exposed Pad","Reference Type":"External, Internal","lifecycle_stage":"eol_hot","Differential Output":"No","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"40-QFN (6x6)","Number of D/A Converters":"16","Voltage - Supply, Analog":"4.75V ~ 5.25V","Voltage - Supply, Digital":"1.71V ~ 5.55V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$60.54","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$60.54000","currency":"USD"},{"qty":10,"price":"$56.87500","currency":"USD"},{"qty":25,"price":"$55.04000","currency":"USD"},{"qty":100,"price":"$51.00370","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ltc2688.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LTC2688HUJ-16#PBF RoHS compliant?","answer":"Yes, it is ROHS3 compliant — no exemptions needed for current EU regulations."},{"question":"Where can I buy LTC2688HUJ-16#PBF?","answer":"This part is sourced to order; availability and pricing are confirmed at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC2688HUJ-16PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC2688HUJ-16PBF when reusing this data.
