It delivers a current output (unbuffered) with a typical settling time of 600 ns, making it suitable for control loops, waveform generation, and precision attenuator applications where update rate matters. The parallel data interface accepts a 12-bit word directly, and the differential output allows the user to configure the output polarity or drive a downstream op-amp for a voltage output. The part operates from a single analog and digital supply rail spanning 5 V to 16 V, which simplifies power distribution on the board. ## Linearity and settling — what they mean for your design The ±0.5 LSB maximum INL and DNL (both at ±0.5 LSB max) means the output code is within half a least-significant bit of the ideal transfer function across all codes. No missing codes at 12-bit resolution. The 600 ns typical settling time to ±0.5 LSB defines the maximum update rate. The external reference input lets you set the full-scale output range independently of the supply rails. ## Package and temperature grade — fit for the board The 18-pin DIP (0.300\" body width, 7.62 mm pitch) is a through-hole package, so this part is a natural fit for prototyping boards, legacy designs, or any build where wave soldering is preferred over reflow. The 0°C to 70°C commercial temperature range limits deployment to controlled indoor environments — office equipment, benchtop instruments, or rack-mount gear — not outdoor or under-hood automotive. The ROHS3 compliance means no lead in the solder finish, which is the current standard for most production runs. ## Sourcing and lifecycle The LTC7541AKN#PBF is listed as Active — no end-of-life notice, no last-time-buy window. That means it remains a viable choice for new designs and production BOMs without the supply-chain risk of an imminent phase-out.","metaTitle":"LTC7541AKN#PBF 12-Bit R-2R DAC, 600ns Settling, 18-DIP","metaDescription":"LTC7541AKN#PBF 12-bit multiplying DAC, R-2R architecture, 600ns settling, ±0.5 LSB INL/DNL, parallel interface, 18-DIP, active production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Output Type":"Current - Unbuffered","Architecture":"R-2R","INL/DNL (LSB)":"±0.5 (Max), ±0.5 (Max)","Mounting Type":"Through Hole","Settling Time":"600ns (Typ)","Data Interface":"Parallel","Number of Bits":"12","Package / Case":"18-DIP (0.300\\\", 7.62mm)","Reference Type":"External","lifecycle_stage":"eol_hot","Differential Output":"Yes","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"18-DIP","Number of D/A Converters":"1","Voltage - Supply, Analog":"5V ~ 16V","Voltage - Supply, Digital":"5V ~ 16V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$12.92000","currency":"USD"},{"qty":10,"price":"$11.87100","currency":"USD"},{"qty":25,"price":"$11.37920","currency":"USD"},{"qty":100,"price":"$10.02600","currency":"USD"},{"qty":250,"price":"$9.53388","currency":"USD"},{"qty":500,"price":"$8.91880","currency":"USD"},{"qty":1000,"price":"$8.18070","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/lt7541a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the resolution of LTC7541AKN#PBF?","answer":"12 bits — the part accepts a 12-bit parallel word and produces a corresponding analog output current."},{"question":"What is LTC7541AKN#PBF's listed output type?","answer":"Current - Unbuffered — the DAC output is a current sink/source that requires an external op-amp or load resistor to convert to a voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC7541AKNPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC7541AKNPBF when reusing this data.
