It delivers a current output (unbuffered) and connects to a host controller via an SPI data interface. The 1 µs settling time and ±1 LSB max INL/DNL make it suited for calibration sources, programmable gain stages, and low-frequency waveform generation where monotonic 12-bit performance is the requirement. ## Supply rails and reference — two supplies, one external reference The DAC uses dual supply rails: the digital interface takes 5 V, while the analog supply accepts 5 V or 11.4 V to 15.75 V. The reference is external. ## Package and temperature grade — prototype-friendly, indoor only Housed in an 8-pin PDIP through-hole package (0.300\" width, 7.62 mm pitch), this DAC is breadboard-friendly and easy to hand-solder for prototypes or low-volume production. The operating temperature range is 0°C to 70°C, which limits it to commercial/indoor environments — not rated for industrial enclosures, outdoor telecom cabinets, or under-hood automotive use. ## Active lifecycle — no end-of-life concern The MAX543BCPA+ carries an Active product status per the manufacturer. There is no NRND or last-time-buy notice in effect.","metaTitle":"MAX543BCPA+ 12-bit DAC, R-2R, SPI, 1µs settling, 8-PDIP","metaDescription":"MAX543BCPA+ 12-bit multiplying DAC with R-2R architecture, SPI interface, and 1µs settling time. 8-PDIP through-hole package, 0°C to 70°C.","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)":"±1 (Max), ±1 (Max)","Mounting Type":"Through Hole","Settling Time":"1µs","Data Interface":"SPI","Number of Bits":"12","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Reference Type":"External","lifecycle_stage":"eol_hot","Differential Output":"No","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"8-PDIP","Number of D/A Converters":"1","Voltage - Supply, Analog":"5V, 11.4V ~ 15.75V","Voltage - Supply, Digital":"5V, 11.4V ~ 15.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$21.99","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$21.99000","currency":"USD"},{"qty":10,"price":"$20.27900","currency":"USD"},{"qty":25,"price":"$19.36760","currency":"USD"},{"qty":100,"price":"$17.31710","currency":"USD"},{"qty":250,"price":"$16.51956","currency":"USD"},{"qty":500,"price":"$15.72206","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX543.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX543BCPA+ RoHS compliant?","answer":"Yes, the part is ROHS3 compliant per the manufacturer's listing."},{"question":"Is MAX543BCPA+ compatible with 5V logic?","answer":"Yes.

The MAX543BCPA+ is the commercial-temperature ±1 LSB grade. An industrial-temperature or higher-accuracy grade (e.g., MAX543BEPA+) would be a drop-in replacement if the application requires a wider temperature range or tighter linearity — verify the specific grade's INL/DNL and temp range against your requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX543BCPA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX543BCPA when reusing this data.
