It settles to within 1/2 LSB in 250 ns typical. ## Package and supply — what to expect on the board This part comes in a 16-pin CERDIP (ceramic dual-in-line) package, through-hole mount. The ceramic body handles rework better than plastic — you can hit it with hot air without worrying about the package cracking, but the thermal mass means you'll want a preheat plate underneath. The supply scheme is split: analog and digital rails both accept ±4.5 V to -16.5 V on the negative side and 5.5 V positive. That bipolar analog supply lets the multiplying DAC swing below ground, which is essential for AC-coupled applications like function generators or audio level control. ## Lifecycle and sourcing — still a current part The DAC1408A-8Q carries an active lifecycle status. That matters if you're qualifying a BOM for a long-run product or maintaining a legacy design that already uses this footprint. The RoHS status is non-compliant, so if your assembly line requires lead-free solder, you'll need to handle this part separately or look for an RoHS-compliant variant. ## What the 250 ns settling time means for your design The 250 ns typical settling time governs how fast the output can change after a new digital code is clocked in. ## Temperature range — commercial only The operating temperature range is 0°C to 75°C — commercial grade. That rules out under-hood automotive, outdoor telecom cabinets in direct sun, or any environment where ambient temperature exceeds 75°C. If your application needs industrial temperature range (-40°C to 85°C), the AD7524JNZ covers that span in a through-hole package, though its settling time is 500 ns and it has differential output. For a drop-in functional alternative with wider temperature, the AD7943BRSZ-REEL is a 12-bit R-2R DAC with ±0.5 LSB INL/DNL, but it's surface-mount and 5 V single-supply only — not a pin-for-pin swap.","metaTitle":"DAC1408A-8Q 8-bit Multiplying DAC, 250ns settling, CERDIP","metaDescription":"DAC1408A-8Q is an 8-bit multiplying D/A converter with 250ns typical settling time in a 16-pin CERDIP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Bulk","Output Type":"Current - Unbuffered","Architecture":"Multiplying DAC, R-2R","Mounting Type":"Through Hole","Settling Time":"250ns (Typ)","Data Interface":"Serial","Number of Bits":"8","Package / Case":"16-CDIP (0.300\\\", 7.62mm)","Reference Type":"External","lifecycle_stage":"eol_hot","Differential Output":"No","Operating Temperature":"0°C ~ 75°C","Supplier Device Package":"16-CERDIP","Number of D/A Converters":"1","Voltage - Supply, Analog":"±4.5V ~ -16.5V, 5.5V","Voltage - Supply, Digital":"±4.5V ~ -16.5V, 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.11","stockQuantity":0,"priceTiers":[{"qty":143,"price":"$2.11000","currency":"USD"}]},"links":{"datasheetUrl":"https://rocelec.widen.net/view/pdf/rsl7ehjjs8/ANDIS08417-1.pdf?t.download=true&u=5oefqw","sourceUrl":null},"ai":{"faq":[{"question":"What is the settling time of DAC1408A-8Q?","answer":"The settling time is 250 ns typical to within 1/2 LSB for a full-scale step.
