In today’s precision-measurement landscape, these devices enable the microvolt-level resolution and long-term stability that professional meters demand.

Maxim Integrated (now within Analog Devices)

Although fully absorbed into Analog Devices, the Maxim legacy lives on through specialized analog and mixed-signal ICs that still carry the design DNA of the original company. Maxim’s historical strength in low-power data converters, sensor interfaces and battery-management devices continues to appear in portable multimeter designs.

The combined ADI-Maxim engineering talent pool exceeds 10,000 people working across a broadened manufacturing network. Many of the original Maxim part numbers remain in production and are still specified by instrument makers who value their low-noise and low-power characteristics. The integration has simply enlarged the catalog available to multimeter designers who need compact, efficient measurement silicon.
