AD7916BRMZ

Overview

The AD7916BRMZ is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates with a sampling rate of 500 kSPS and accepts differential input signals. The device functions on dual 2.5 V power supplies, with an analog supply range of 2.375 V to 2.625 V and a digital supply range of 2.375 V to 2.625 V. It features a signal-to-noise ratio of 94 dB and dissipates 4.5 mW of power. The component utilizes an external reference type and communicates via 3-Wire, Microwire, or SPI interfaces. It is housed in a 10-MSOP package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Supports high-resolution 16-bit data conversion with a 500 kSPS sampling rate for precise signal acquisition.
• Features low power consumption of 4.5 mW, suitable for battery-powered or energy-efficient applications.
• Offers flexible digital interface compatibility with standard 3-Wire, Microwire, and SPI protocols.
• Designed for industrial environments with an extended operating temperature range up to +125°C.

Applications

• Industrial process control systems requiring high accuracy
• Medical instrumentation and diagnostic equipment
• Data acquisition systems for sensor interfacing

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing components. Confirm RoHS compliance status and manufacturing origin through official distributor channels. Ensure the supplier provides valid traceability documentation. Check for any regional distribution restrictions that may affect availability. Validate the part number against the manufacturer's current product portfolio to avoid obsolete stock.

Selection Notes

Select this component for applications demanding 16-bit resolution at moderate speeds. Consider the differential input requirement and external reference necessity during circuit design. Evaluate the MSOP-10 package constraints for PCB layout. Compare power dissipation specifications against thermal management capabilities. Verify interface compatibility with the host microcontroller or DSP system.

Part Context

This part belongs to the AD7916 series of PulSAR ADCs. It shares architectural similarities with other members like the AD7915 but differs in sampling speed. The BRMZ suffix indicates the industrial temperature grade and MSOP packaging. It is distinct from higher-speed variants such as the AD7980 series.

Replacement Considerations

The AD7915BRMZ offers similar resolution but with a higher 1 MSPS sampling rate. The AD7916ARMz is the same electrical specification in an LFCSP package. Verify pinout compatibility before substituting between package types.
