AD7923WYRUZ-REEL7

Overview

The AD7923WYRUZ-REEL7 is a 12-bit, high-speed, low-power successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It features four single-ended analog inputs managed by an integrated channel sequencer and operates from a single 2.7 V to 5.25 V power supply. The device supports throughput rates up to 200 kSPS with a maximum power dissipation of 7.5 mW at 5 V. It utilizes a wide-bandwidth track-and-hold amplifier capable of handling input frequencies exceeding 8 MHz. The component is housed in a 16-lead TSSOP package and is qualified for automotive applications.

Feature Summary

• Four single-ended analog inputs with a programmable channel sequencer for automated sequential conversions.
• Flexible power management capabilities including auto-shutdown and full shutdown modes to minimize current consumption.
• VDRIVE function enabling the serial interface to operate independently at either 3 V or 5 V logic levels.
• High-speed SPI/QSPI/MICROWIRE/DSP-compatible serial interface with no pipeline delays.

Applications

• Automotive sensor signal conditioning
• Industrial process control systems
• Data acquisition modules

Procurement Notes

Verify that the specific suffix REEL7 corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the B version temperature range meets the operational requirements of the target environment. Ensure compatibility with external reference voltage specifications before finalizing procurement orders.

Selection Notes

Select this component when a 12-bit resolution and 200 kSPS sampling rate are required for multi-channel applications. Consider the VDRIVE feature if interfacing with processors operating at different voltage levels than the analog supply. Evaluate the power consumption profiles against system battery life constraints, particularly utilizing the auto-shutdown mode for intermittent sampling tasks.

Part Context

This part belongs to the AD7923 family of 4-channel SAR ADCs. The WYRUZ designation indicates the automotive-grade qualification and the TSSOP-16 package type. The REEL7 suffix specifies the manufacturing packaging configuration. This model represents a specialized variant designed for robust performance in demanding environments compared to standard commercial versions.

Replacement Considerations

Direct replacements within the same family include the AD7923BRUZ for commercial grade applications. For automotive contexts, verify availability of equivalent automotive-qualified parts with identical pinouts and electrical characteristics. Cross-referencing should focus on maintaining the 12-bit resolution and 4-channel architecture.
