Replacement verdict
Compatible functional replacement candidate
The AD5320BRMZ and AD5320BRM are functionally equivalent 12-bit DACs from the same family, sharing identical resolution, interface, and electrical characteristics. The only meaningful distinction is the package finish, where the Z suffix denotes a RoHS-compliant lead-free version. Designers can treat the AD5320BRMZ as a direct functional substitute for the AD5320BRM, with the added benefit of environmental compliance.

Key electrical and mechanical differences between the two devices
| Parameter | AD5320BRMZ | AD5320BRM | Why it matters |
|---|---|---|---|
| Resolution | 12 bit | 12 bit | Determines the smallest analog output step; identical resolution means equivalent output granularity. |
| Number of DAC Channels | 1 | 1 | Defines how many independent analog outputs are available; must match for direct substitution. |
| Interface Type | SPI / QSPI / MICROWIRE / DSP compatible | SPI / QSPI / MICROWIRE / DSP compatible | The digital communication protocol must be compatible with the host controller for drop-in replacement. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Determines compatibility with the system power rail; identical range ensures the same operating conditions. |
| Output Type | Voltage, buffered | Voltage, buffered | Buffered voltage output allows direct driving of loads without external amplifiers; must match for functional equivalence. |
| Reference Type | External | External | Indicates whether an internal reference is available; external reference requires the same board-level reference design. |
| Operating Temperature Range | -40 °C to +105 °C | -40 °C to +105 °C | Ensures both parts function over the same environmental conditions for industrial-grade applications. |
| Package / Mounting Type | 8-Lead MSOP, Surface Mount | 8-Lead MSOP, Surface Mount | The physical footprint and mounting style must match for PCB compatibility; both use the same MSOP package. |
| RoHS Compliance | RoHS Compliant | Non-RoHS / Leaded | RoHS status affects regulatory compliance and solder process compatibility; the Z suffix denotes lead-free construction. |
| Packaging / Ordering Suffix | Z = RoHS-compliant, tube or reel | Standard leaded, tube or reel | The ordering suffix distinguishes lead-free versus leaded versions, which impacts procurement and assembly compliance. |

Frequently asked questions
What is the difference between the AD5320BRMZ and the AD5320BRM?
The AD5320BRMZ and AD5320BRM are functionally identical 12-bit digital-to-analog converters. The primary difference is the package and ordering suffix: the AD5320BRMZ is a lead-free, RoHS-compliant version in an 8-lead MSOP package, while the AD5320BRM is the non-RoHS version of the same device in the same 8-lead MSOP package.
Are the AD5320BRMZ and AD5320BRM pin-compatible?
Yes. Both devices are offered in the same 8-lead MSOP package and share the same pinout, allowing them to be used interchangeably on the same PCB footprint when RoHS compliance is not a constraint.
Can the AD5320BRMZ directly replace the AD5320BRM in an existing design?
Yes, the AD5320BRMZ can directly replace the AD5320BRM in most designs because they share the same electrical specifications, package, and pinout. The only consideration is that the AD5320BRMZ is lead-free and RoHS-compliant, which may affect soldering process requirements.
What are the key specifications of the AD5320BRMZ and AD5320BRM?
Both devices are 12-bit buffered voltage output DACs with a single supply range of 2.7 V to 5.5 V, a low power consumption of typically 140 µA at 3 V, and an I2C-compatible serial interface. They are specified over the industrial temperature range of −40°C to +105°C.
Is the AD5320BRMZ RoHS compliant while the AD5320BRM is not?
Yes. The "Z" suffix in AD5320BRMZ indicates a lead-free, RoHS-compliant package. The AD5320BRM without the "Z" suffix is the non-RoHS version that contains lead in the package terminal finish.
Do the AD5320BRMZ and AD5320BRM have the same operating temperature range?
Yes. Both the AD5320BRMZ and AD5320BRM are specified for the industrial temperature range of −40°C to +105°C, as stated in the Analog Devices datasheet.
Which part should be selected for a new design, the AD5320BRMZ or the AD5320BRM?
For new designs, the AD5320BRMZ is generally recommended because it is RoHS-compliant and lead-free, meeting current environmental regulations. The AD5320BRM may still be used for existing designs or where non-RoHS assembly processes are required.
