AD7924BRUZ-REEL7

Overview

The AD7924BRUZ-REEL7 is a 12-bit, 4-channel successive approximation analog-to-digital converter (ADC) from Analog Devices. It operates on a single supply voltage ranging from 2.7 V to 5.25 V and achieves throughput rates up to 1 MSPS. The device features four single-ended analog inputs with an integrated channel sequencer. It utilizes a flexible serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. Power consumption reaches a maximum of 13.5 mW at 5 V supplies during operation. The component is housed in a 16-lead TSSOP package.

Feature Summary

• Integrated channel sequencer for automated sequential conversion of multiple single-ended inputs
• Flexible power management with full shutdown mode reducing current to 0.5 µA maximum
• VDRIVE function enabling direct connection to 3 V or 5 V processor systems independent of AVDD
• No pipeline delays associated with the successive approximation conversion process

Applications

• Industrial process control systems requiring multi-channel data acquisition
• Battery-powered instrumentation benefiting from low power consumption
• Automotive applications due to qualification for automotive environments
• Data acquisition modules interfacing with microprocessors or DSPs

Procurement Notes

Verify the specific suffix BRUZ against the official Analog Devices ordering guide to confirm the temperature range and packaging configuration. Ensure the REEL7 designation matches the required tape and reel quantity for production integration. Cross-reference the datasheet revision C specifications with the manufacturing date code to ensure compliance with current quality standards.

Selection Notes

Select this component when 12-bit resolution and 1 MSPS throughput are required for four single-ended channels. Consider the AD7924 over the AD7914 or AD7904 if higher dynamic performance and lower noise are necessary. Evaluate the external reference requirement, as specified performance depends on a stable 2.5 V ±1% REFIN input. Confirm that the serial interface timing aligns with the host controller's capabilities.

Part Context

This part belongs to the AD7904/AD7914/AD7924 family of high-speed, low-power ADCs. The AD7924 variant specifically provides 12-bit resolution, distinguishing it from the 8-bit AD7904 and 10-bit AD7914 models within the same package and feature set. All variants share identical pinouts and control logic, facilitating design scalability across different resolution requirements.

Replacement Considerations

The AD7924WYRUZ-REEL7 serves as a qualified alternative with an extended operating temperature range up to +125°C. Verify thermal management requirements if the application environment exceeds the standard commercial limit of +85°C.
