Key electrical and mechanical differences between the two devices
| Parameter | AD5322BRM | AD5322BRM-REEL7 | Why it matters |
|---|---|---|---|
| Number of DAC Channels | 2 | 2 | Determines how many independent analog outputs the device can drive; must match for functional substitutability. |
| Resolution | 12 bits | 12 bits | Sets the output voltage granularity; identical resolution ensures equivalent precision in the target application. |
| Interface Type | SPI / QSPI / MICROWIRE / DSP compatible | SPI / QSPI / MICROWIRE / DSP compatible | Defines the digital communication protocol; matching interfaces allow drop-in replacement without firmware changes. |
| Supply Voltage Range | 2.5 V to 5.5 V | 2.5 V to 5.5 V | Determines compatibility with the system power rail; identical ranges ensure the same operating conditions. |
| Package / Case | 10-TFSOP, 10-MSOP (0.118 in, 3.00 mm width) | 10-TFSOP, 10-MSOP (0.118 in, 3.00 mm width) | Physical footprint and mounting must match for PCB layout compatibility. |
| Mounting Type | Surface Mount | Surface Mount | Assembly method must be identical for the part to be used on the same board. |
| Operating Temperature Range | -40°C to 105°C | -40°C to 105°C | Ensures the device operates reliably in the same environmental conditions. |
| Output Type | Voltage - Buffered | Voltage - Buffered | Defines the electrical behavior of the DAC output; must match to drive the same load circuitry. |
| Reference Type | External | External | Determines whether an external voltage reference is required; matching type ensures the same system design works. |
| Packaging | Tube | Tape & Reel | Affects manufacturing handling and assembly equipment; different packaging may require different production processes. |

Frequently asked questions
What is the difference between AD5322BRM and AD5322BRM-REEL7?
The AD5322BRM and AD5322BRM-REEL7 are the same device. The AD5322BRM is the base part number for the 10-lead MSOP package, while the -REEL7 suffix indicates the packaging option: tape and reel with 750 units per reel. Both share identical electrical specifications, die, and package type.
Are the AD5322BRM and AD5322BRM-REEL7 electrically identical?
Yes. Both part numbers refer to the same silicon die and package. The AD5322 is a dual 12-bit DAC with an SPI interface, and the -REEL7 suffix only changes the shipping format, not the electrical performance or functional behavior.
Can the AD5322BRM and AD5322BRM-REEL7 be used interchangeably in a design?
Yes, they are interchangeable. Since the -REEL7 version is simply the tape-and-reel packaged variant of the same device, either can be used in the same PCB footprint and circuit. The only practical difference is the packaging format for automated assembly.
What is the package type for the AD5322BRM and AD5322BRM-REEL7?
Both parts are offered in a 10-lead MSOP (Mini Small Outline Package). The package code "RM" in the part number denotes this MSOP package. The -REEL7 option does not change the package dimensions or pinout.
What is the resolution and number of DAC channels for the AD5322BRM and AD5322BRM-REEL7?
The AD5322 is a dual-channel, 12-bit digital-to-analog converter. Both the AD5322BRM and AD5322BRM-REEL7 provide two independent 12-bit DAC outputs with a serial SPI interface.
What is the operating temperature range for the AD5322BRM and AD5322BRM-REEL7?
The AD5322BRM and AD5322BRM-REEL7 are specified over the industrial temperature range of -40°C to +105°C. This is consistent across both packaging variants.
Does the -REEL7 suffix affect the moisture sensitivity level (MSL) of the AD5322BRM?
No. The MSL rating is determined by the package and assembly process, not the shipping format. Both the AD5322BRM and AD5322BRM-REEL7 share the same MSL rating as specified in the manufacturer's datasheet for the 10-lead MSOP package.
Which part number should be used for automated pick-and-place assembly?
The AD5322BRM-REEL7 is the preferred choice for automated pick-and-place assembly because it is supplied in tape and reel packaging. The AD5322BRM may be supplied in tubes or trays, which are less suitable for high-volume automated assembly.
