Key electrical and mechanical differences between the two devices
| Parameter | AD5543BRMZ | AD5543BRM | Why it matters |
|---|---|---|---|
| Resolution | 16 bits | 16 bits | Both parts provide the same DAC resolution, so they are functionally equivalent in terms of output precision. |
| Number of DAC Channels | 1 | 1 | Identical channel count means either part can serve the same single-channel signal generation role. |
| Interface Type | SPI | SPI | The same serial interface ensures both parts are compatible with the same host controller and firmware. |
| Supply Voltage | 5 V | 5 V | Matching supply requirements allow either device to be used in the same power architecture. |
| Package Type | 10-Lead MSOP | 10-Lead MSOP | The same package footprint means the parts are physically interchangeable on a PCB. |
| Operating Temperature Range | -40°C to +125°C | -40°C to +85°C | The wider temperature range of the BRMZ version makes it suitable for more demanding industrial or automotive environments. |
| RoHS Compliance | RoHS Compliant | Non-RoHS | RoHS compliance affects regulatory acceptance and environmental disposal requirements in many markets. |
| Lead Finish | Matte Tin | Tin/Lead | Different lead finishes influence solderability, whisker risk, and compliance with lead-free manufacturing processes. |

Frequently asked questions
What is the difference between the AD5543BRMZ and the AD5543BRM?
The AD5543BRMZ is the RoHS-compliant, lead-free version of the AD5543BRM. Both are 16-bit current-output digital-to-analog converters in a 10-lead MSOP package. The primary difference is the package/ordering option: the "Z" suffix indicates RoHS compliance and a lead-free assembly, while the AD5543BRM is the non-RoHS version. Electrical specifications and functional operation are identical per the Analog Devices datasheet.
Are the AD5543BRMZ and AD5543BRM electrically and functionally interchangeable?
Yes. Both devices share the same 16-bit resolution, current-output R-2R architecture, SPI-compatible serial interface, and specified operating temperature range. The AD5543BRMZ is simply the RoHS-compliant ordering variant of the AD5543BRM, so they are functionally interchangeable in designs that do not have a specific non-RoHS requirement.
What is the resolution and architecture of the AD5543BRMZ and AD5543BRM?
Both are 16-bit multiplying DACs using a current-output R-2R ladder architecture. They provide 16-bit resolution with a serial input interface and are specified for operation from a single +5 V supply or dual ±5 V supplies, depending on the configuration.
What package do the AD5543BRMZ and AD5543BRM use?
Both devices are offered in a 10-lead MSOP (Mini Small Outline Package). The AD5543BRMZ is the lead-free/RoHS-compliant version of the same 10-lead MSOP package used by the AD5543BRM.
Can the AD5543BRMZ be used as a drop-in replacement for the AD5543BRM?
Yes, from a functional and footprint perspective. Both use the same 10-lead MSOP package with identical pinout and electrical specifications. The AD5543BRMZ is the RoHS-compliant variant, so it can be used as a drop-in replacement where RoHS compliance is required or preferred, provided the assembly process supports lead-free soldering.
What is the interface type of the AD5543BRMZ and AD5543BRM?
Both devices use a 3-wire SPI-compatible serial interface for loading the DAC register. The interface supports clock rates up to 50 MHz per the Analog Devices datasheet, enabling high-speed updates in precision control applications.
Do the AD5543BRMZ and AD5543BRM differ in accuracy or temperature drift specifications?
No. Both the AD5543BRMZ and AD5543BRM are specified with the same 16-bit resolution, integral nonlinearity (INL), differential nonlinearity (DNL), and gain/offset temperature drift characteristics as published in the Analog Devices AD5543 datasheet. The "Z" suffix denotes RoHS compliance only and does not change the electrical performance specifications.
