AD7916BRMZ-RL7

Overview

The AD7916BRMZ-RL7 is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates with a sampling rate of 500 kSPS and features a differential input architecture. The device requires external reference voltage and is powered by a 2.5 V analog supply and a 2.5 V digital supply. It achieves a signal-to-noise ratio (SNR) of 94 dB. Power dissipation is specified at 4.5 mW. The component supports 3-Wire, Microwire, and SPI serial interfaces and is housed in a 10-lead MSOP package. It functions within an operating temperature range from -40°C to +125°C.

Feature Summary

• High-resolution 16-bit data conversion capability with low power consumption
• Flexible serial interface compatibility supporting standard communication protocols
• Differential input structure for improved noise immunity

Applications

• Data acquisition systems requiring high precision
• Industrial process control applications
• Medical instrumentation equipment

Procurement Notes

Verify the specific ordering suffix RL7 confirms reel packaging when sourcing components. Confirm that the BRMZ designation corresponds to the commercial temperature grade and MSOP package type required for the design. Ensure the manufacturer is identified as Analog Devices Inc. to guarantee authenticity and performance specifications match the datasheet requirements.

Selection Notes

Select this component when a 16-bit resolution and 500 kSPS throughput are required for differential signals. Consider the external reference requirement and the specific 2.5 V supply constraints. Evaluate the MSOP-10 package dimensions against the available PCB space. Compare power dissipation characteristics against system thermal limits to ensure adequate heat management during operation.

Part Context

This part belongs to the AD7916 series of PulSAR ADCs. It shares architectural similarities with the AD7915 but offers a lower sampling rate of 500 kSPS compared to the 1 MSPS variant. Both devices utilize the same 10-lead MSOP footprint and SAR technology, providing designers with options based on speed versus power trade-offs within the same family.

Replacement Considerations

The AD7915BRMZ-RL7 serves as a higher-speed alternative within the same package. Verify if the increased 1 MSPS sampling rate meets system requirements without exceeding power budgets. Check pinout compatibility to ensure direct substitution is feasible without schematic modifications.
