AD7924BRU-REEL7

Analog To Digital Converters (ADC) Overview

The AD7924BRU-REEL7 is a 12-bit, 4-channel successive approximation analog-to-digital converter (ADC) from Analog Devices. It operates on a single 2.7 V to 5.25 V supply with a maximum throughput rate of 1 MSPS. The device features four single-ended analog inputs managed by an internal sequencer and includes a low-noise track-and-hold amplifier capable of handling input frequencies exceeding 8 MHz. Power consumption reaches a maximum of 13.5 mW at 5 V supplies during operation. It utilizes a flexible serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The component is housed in a 16-lead TSSOP package and supports automotive qualification.

Analog To Digital Converters (ADC) Feature Summary

• Integrated channel sequencer for automated multi-channel conversion sequences
• VDRIVE function enabling direct interfacing with 3 V or 5 V processor systems independent of AVDD
• Flexible power management with two shutdown modes reducing current to 0.5 µA maximum
• Standard successive approximation architecture ensuring no pipeline delays

Analog To Digital Converters (ADC) Applications

• Industrial process control data acquisition systems
• Medical equipment requiring multi-channel signal monitoring
• Battery-powered portable instrumentation
• Automotive electronic measurement modules

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against official documentation to confirm temperature range and automotive qualification status. Ensure the external reference voltage is set to 2.5 V ±1% for specified performance. Confirm that the logic supply voltage matches the target microprocessor interface requirements before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 12-bit resolution and 1 MSPS throughput are required for single-ended signals. Compare against AD7914 for lower resolution needs or AD7927 for higher channel counts. Consider the W version if extended temperature ranges up to +125°C are necessary for the application environment.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD7904/AD7914/AD7924 family of high-speed, low-power ADCs. The family shares identical pinouts and functional architectures, differing primarily in resolution: 8-bit, 10-bit, and 12-bit respectively. All variants support the same 1 MSPS throughput and feature the integrated sequencer and VDRIVE functionality within the 16-lead TSSOP package.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include AD7924ARUZ and AD7924ARMZ. Verify that alternative packages maintain compatibility with existing PCB footprints and thermal requirements.
