AD7983BRMZ-RL7

Overview

The AD7983BRMZ-RL7 is a 16-bit successive approximation analog-to-digital converter (ADC) from Analog Devices, operating at a throughput of 1.33 MSPS. It features a pseudo-differential input range of 0 V to VREF with an external reference voltage between 2.9 V and 5 V. Powered by a single 2.5 V supply, it consumes 10.5 mW at maximum speed. The device includes a versatile serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting daisy-chaining and busy indicators. It operates within a temperature range of -40°C to +85°C and is housed in a 10-lead MSOP package.

Feature Summary

• Zero latency architecture providing immediate data availability after conversion completion without pipeline delay.
• Versatile serial interface supporting multiple modes including daisy-chaining for multiple ADCs on a single bus.
• Low power dissipation that scales linearly with throughput, enabling efficient operation in battery-powered applications.

Applications

• Automated test equipment
• Data acquisition systems
• Medical instruments
• Machine automation

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging format required for your assembly line. Confirm that the BRMZ variant meets the industrial temperature specifications needed for your deployment environment. Ensure compatibility with existing PCB footprints for the 10-lead MSOP package before finalizing procurement orders.

Selection Notes

Select this component when a high-resolution 16-bit ADC with low power consumption is required for space-constrained designs. The pseudo-differential input configuration simplifies signal conditioning compared to fully differential architectures. Consider the separate VIO supply pin if interfacing with logic families other than the primary 2.5 V digital supply.

Part Context

This part belongs to the PulSAR family of precision SAR ADCs from Analog Devices. It shares architectural similarities with the AD7982 but offers lower resolution. The device is designed for applications requiring high accuracy and moderate sampling rates, fitting into the broader portfolio of data acquisition solutions provided by the manufacturer.

Replacement Considerations

The AD7982 is pin-for-pin compatible but provides 18-bit resolution. Verify if the additional resolution is necessary or if the lower cost of the AD7983 is preferred. Other family members like the AD7980 offer similar performance with different input configurations.
