Replacement verdict
Compatible functional replacement candidate
The AD5324BRMZ is a functionally compatible replacement candidate for the AD5324BRM, sharing the same quad 12-bit DAC architecture, 10-lead MSOP footprint, and specified operating temperature range. The primary distinction is the RoHS-compliant lead-free construction of the BRMZ grade versus the lead-containing BRM grade, which may require validation for applications with specific soldering process or regulatory requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD5324BRMZ | AD5324BRM | Why it matters |
|---|---|---|---|
| Number of DAC Channels | 4 | 4 | Determines how many independent analog outputs the device can drive; must match for functional substitutability. |
| DAC Resolution | 12 bits | 12 bits | Sets the output voltage granularity; identical resolution ensures equivalent precision in the target application. |
| Supply Voltage Range | 2.5 V to 5.5 V | 2.5 V to 5.5 V | Defines the operating voltage window; matching ranges allow the parts to be used in the same power architecture. |
| Interface Type | SPI / QSPI / MICROWIRE / DSP compatible | SPI / QSPI / MICROWIRE / DSP compatible | Determines host controller compatibility; identical serial interfaces permit drop-in replacement without firmware changes. |
| Output Type | Voltage output, buffered | Voltage output, buffered | Specifies whether the DAC drives a voltage or current signal; must match to preserve signal chain behavior. |
| Reference Input | External | External | Indicates whether an internal or external reference is used; matching reference topology ensures consistent full-scale output. |
| Package / Mounting | 10-Lead MSOP, Surface Mount | 10-Lead MSOP, Surface Mount | Package and mounting style affect PCB footprint and assembly; differences would require layout changes. |
| RoHS Compliance | RoHS Compliant | Non-RoHS / Leaded | RoHS status affects regulatory compliance and solder process compatibility; non-compliant parts may not be usable in all markets. |
| Operating Temperature Range | -40 °C to +105 °C | -40 °C to +105 °C | Defines the environmental limits for reliable operation; matching ranges ensure the same application conditions apply. |
| INL (Integral Nonlinearity) | ±1 LSB max | ±1 LSB max | Specifies DAC accuracy; identical INL guarantees equivalent linearity performance in precision applications. |

Frequently asked questions
What is the difference between the AD5324BRMZ and the AD5324BRM?
The AD5324BRMZ and AD5324BRM are both quad 12-bit DACs from Analog Devices. The primary difference is the package and lead finish: the AD5324BRM is supplied in a 10-lead MSOP (RM-10) package, while the AD5324BRMZ is the same device in a 10-lead MSOP package with a lead-free, RoHS-compliant finish. The "Z" suffix indicates RoHS compliance.
Are the AD5324BRMZ and AD5324BRM functionally interchangeable?
Yes, they are functionally identical. Both have the same 12-bit resolution, four DAC channels, 2.5 V to 5.5 V supply range, and SPI-compatible serial interface. The only difference is the package finish (lead-free vs. leaded), so they can be interchanged in most designs, provided the PCB assembly process supports the respective finish.
What is the resolution and number of DAC channels for these devices?
Both the AD5324BRMZ and AD5324BRM are quad, 12-bit digital-to-analog converters, providing four independent DAC channels with 12-bit resolution.
What is the supply voltage range for the AD5324BRMZ and AD5324BRM?
Both devices operate from a single supply voltage of 2.5 V to 5.5 V, as specified in the Analog Devices datasheet.
What serial interface do the AD5324BRMZ and AD5324BRM use?
Both parts use a 3-wire SPI-compatible serial interface that operates at clock rates up to 30 MHz, allowing easy connection to microcontrollers and DSPs.
Do the AD5324BRMZ and AD5324BRM have the same package dimensions and pinout?
Yes, both are offered in the same 10-lead MSOP package with identical pinout and dimensions. The only physical difference is the lead finish: the AD5324BRMZ is lead-free/RoHS-compliant, while the AD5324BRM has a standard tin-lead finish.
Which part should be selected for a new RoHS-compliant design?
For new designs requiring RoHS compliance, the AD5324BRMZ should be selected because it has a lead-free finish and meets RoHS requirements. The AD5324BRM is the non-RoHS version and is typically used for legacy or military/aerospace applications where leaded finishes are still permitted.
Are the AD5324BRMZ and AD5324BRM available in tape and reel packaging?
Yes, both parts are available in tape and reel packaging. The AD5324BRMZ is typically ordered as AD5324BRMZ-REEL or AD5324BRMZ-REEL7, and the AD5324BRM as AD5324BRM-REEL or AD5324BRM-REEL7, depending on the quantity per reel.
