It settles to within ±0.5 LSB in 1 µs, making it suitable for control-loop and waveform-generation applications where two independent analog outputs share a common reference. Data is written via a parallel interface, which gives deterministic latency — no serial clock dependency — so the update timing is set by the host's write strobe alone. The external reference type means the full-scale output range tracks whatever reference voltage you supply, from 5 V to 15 V on both the analog and digital rails. ## Industrial temperature grade and surface-mount package The 24-SOIC (7.50 mm wide) body is a standard footprint for 8- to 14-bit converters; the wide-body SOIC gives better thermal coupling to the PCB copper than the narrow version. Supplied in a tube, the part is MSL-rated per the standard JEDEC profile for the package. The surface-mount leads are tin-plated and compatible with lead-free reflow — no special bake required if the moisture barrier bag is intact and the floor life has not been exceeded. ## How it compares to the AD7545AKRZ-REEL7 The closest functional peer listed is the AD7545AKRZ-REEL7. Both are 12-bit, R-2R, current-unbuffered DACs with 1 µs settling and a parallel interface. The DAC8221FSZ gives you two DAC channels in one package versus the AD7545's single channel, and its INL/DNL is tighter (±0.4 / ±0.2 LSB) compared to the AD7545's ±0.5 / ±1 LSB max. If your BOM calls for a dual DAC in the same package width, the DAC8221FSZ is the drop-in upgrade without a board spin.","metaTitle":"DAC8221FSZ Analog Devices 12-bit dual DAC, 1µs, 24-SOIC","metaDescription":"DAC8221FSZ 12-bit dual DAC from Analog Devices, current-unbuffered output, 1µs settling, R-2R architecture, parallel interface, 24-SOIC tube.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Output Type":"Current - Unbuffered","Architecture":"R-2R","INL/DNL (LSB)":"±0.4, ±0.2","Mounting Type":"Surface Mount","Settling Time":"1µs","Data Interface":"Parallel","Number of Bits":"12","Package / Case":"24-SOIC (0.295\\\", 7.50mm Width)","Reference Type":"External","lifecycle_stage":"eol_hot","Differential Output":"No","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"24-SOIC","Number of D/A Converters":"2","Voltage - Supply, Analog":"5V ~ 15V","Voltage - Supply, Digital":"5V ~ 15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$69.31","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$69.31000","currency":"USD"},{"qty":10,"price":"$65.11200","currency":"USD"},{"qty":25,"price":"$63.01160","currency":"USD"},{"qty":100,"price":"$59.44500","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the output type of the DAC8221FSZ?","answer":"The DAC8221FSZ has a current-unbuffered output. This means the output is a current proportional to the digital code and the external reference voltage, without an internal op-amp buffer. An external I-V conversion stage (e.g., an op-amp) is typically used to convert the current to a voltage."},{"question":"Will the DAC8221FSZ drop into a board designed for the AD7545AKRZ-REEL7?","answer":"Not without changes. The DAC8221FSZ is a dual DAC in a 24-SOIC package, while the AD7545AKRZ-REEL7 is a single DAC in a 20-SOIC package. The pinouts and channel count differ, so a board spin or adapter is required. However, the DAC8221FSZ offers two channels and wider temperature range, so it may be a functional upgrade if the board layout can accommodate the extra pins."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DAC8221FSZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DAC8221FSZ when reusing this data.
