AD7915BRMZ-RL7

Overview

The AD7915BRMZ-RL7 is a 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) from the PulSAR family. It features a single differential input channel and supports sampling rates up to 1 MSPS. The device operates on a 2.5 V analog and digital supply, consuming 9 mW of power dissipation. It utilizes an external reference voltage with a maximum rating of 5.1 V. Key performance metrics include a signal-to-noise ratio (SNR) of 94 dB. The component is housed in a 10-lead MSOP package and supports 3-Wire, Microwire, and SPI serial interfaces. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Low power consumption with linear scaling relative to throughput
• Flexible serial interface compatibility including SPI and Microwire
• High resolution with 16-bit accuracy and no missing codes
• Wide operating temperature range for industrial applications

Applications

• Data acquisition systems
• Industrial process control
• Medical equipment

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact pinout and electrical specifications required for the design. Check RoHS compliance status through official documentation before integration.

Selection Notes

Select this component for applications requiring high resolution at moderate speeds. Compare against AD7916 if lower power at reduced speed is needed. Verify that the external reference voltage capability aligns with system requirements. Ensure the MSOP package fits the PCB layout constraints.

Part Context

This part belongs to the AD7915/AD7916 series of low-power, 16-bit SAR ADCs. It shares architectural similarities with other PulSAR devices but offers specific performance trade-offs between speed and power. The BRMZ suffix denotes the commercial temperature grade and MSOP package type.

Replacement Considerations

The AD7916BRMZ-RL7 is a related variant offering 500 kSPS speed with lower power consumption. Both share the same package and interface. Verify if the reduced speed of the alternative meets system timing requirements.
