Replacement verdict
Compatible functional replacement candidate
The AD5684RBRUZ and AD5684RBRUZ-RL7 are functionally identical quad-channel 12-bit nanoDAC+ converters sharing the same silicon die, electrical specifications, and 16-lead TSSOP package. The only distinction is the packaging format: the base part number is supplied in tubes, while the -RL7 suffix denotes tape-and-reel packaging for automated assembly. Either variant can be used interchangeably in the same PCB footprint and application circuit without any design modification.

Frequently asked questions
What is the difference between AD5684RBRUZ and AD5684RBRUZ-RL7?
The AD5684RBRUZ and AD5684RBRUZ-RL7 are functionally identical quad-channel 12-bit nanoDAC+ devices with an on-chip 2.5 V reference. The only difference is the packaging format: AD5684RBRUZ is supplied in a tube, while AD5684RBRUZ-RL7 is supplied in a 7-inch reel with 1,000 pieces per reel for automated pick-and-place assembly.
Are AD5684RBRUZ and AD5684RBRUZ-RL7 electrically and functionally interchangeable?
Yes. Both orderable part numbers refer to the same silicon die, package type (16-lead TSSOP), pinout, and specified performance. They differ only in the shipping container and quantity per container, so they are interchangeable in the target design.
What are the key specifications of the AD5684R family?
The AD5684R is a quad-channel, 12-bit digital-to-analog converter with an integrated 2.5 V, 2 ppm/°C reference. It operates from a single 2.7 V to 5.5 V supply, offers a relative accuracy (INL) of ±1 LSB maximum, and supports a 50 MHz SPI interface. It is specified over the −40 °C to +105 °C temperature range.
What package and pin count do AD5684RBRUZ and AD5684RBRUZ-RL7 use?
Both parts are offered in a 16-lead TSSOP (Thin Shrink Small Outline Package) with a 4.4 mm body width. The "RU" suffix in the part number denotes the TSSOP package, and "Z" indicates a RoHS-compliant lead-free finish.
Which applications are suitable for the AD5684RBRUZ and AD5684RBRUZ-RL7?
Typical applications include process control and industrial automation, programmable logic controllers (PLCs), data acquisition systems, portable instrumentation, and digital gain and offset adjustment. The integrated reference and small package make them suitable for space-constrained, precision control loops.
What is the difference in moisture sensitivity level (MSL) between the two orderable part numbers?
Both AD5684RBRUZ and AD5684RBRUZ-RL7 are rated at MSL 1, indicating unlimited floor life at ≤30 °C and ≤85% relative humidity. The MSL rating is determined by the package and die attach, which are identical for both orderable part numbers.
Can AD5684RBRUZ-RL7 be used in a design that was qualified with AD5684RBRUZ?
Yes, provided the assembly process is compatible with reeled components. Since the die, package, and electrical specifications are identical, no requalification of the device performance is required. However, the reel packaging may require verification of the pick-and-place feeder setup and reel dimensions.
What is the operating temperature range for AD5684RBRUZ and AD5684RBRUZ-RL7?
Both devices are specified for operation over the industrial temperature range of −40 °C to +105 °C. This rating applies to both the tube and reel orderable part numbers, as they share the same silicon and package construction.
