AD7927WYRUZ-REEL7

Overview

The AD7927WYRUZ-REEL7 is an automotive-grade, 12-bit successive approximation analog-to-digital converter featuring eight single-ended inputs and a built-in channel sequencer. It operates from a single 2.7 V to 5.25 V supply with throughput rates up to 200 kSPS. The device includes a wide bandwidth track-and-hold amplifier capable of handling input frequencies exceeding 8 MHz. It offers flexible power management modes, including full shutdown consuming 0.5 μA maximum. The component utilizes a high-speed serial interface compatible with SPI, QSPI, Microwire, and DSP standards, packaged in a 20-lead TSSOP.

Feature Summary

• Eight single-ended analog inputs managed by a programmable channel sequencer for automated conversion cycles.
• Automotive qualification compliant with AEC-Q100 standards for extended temperature reliability.
• VDRIVE function enabling direct connection to 3 V or 5 V processor systems independent of the analog supply voltage.
• Flexible power management allowing operation in normal mode or deep shutdown states to minimize energy consumption.

Applications

• Industrial process control systems requiring multi-channel data acquisition.
• Automotive sensor interfaces for monitoring vehicle subsystems.
• Battery management systems within electric vehicles.
• Medical instrumentation devices requiring precise signal digitization.

Procurement Notes

Verify the specific suffix REEL7 indicates reel packaging when sourcing components. Confirm that the W designation corresponds to the automotive grade variant with an operating temperature range extending to +125°C. Ensure compatibility with the required serial communication protocol before integration into the design.

Selection Notes

Select this component when an automotive-rated ADC with multiple single-ended channels is required. The integrated sequencer reduces microprocessor overhead compared to standard multiplexed converters. Consider the external reference requirement and the specific input voltage ranges supported by the RANGE bit configuration during system design.

Part Context

This part belongs to the AD7927 family of high-speed, low-power analog-to-digital converters manufactured by Analog Devices Inc. The family shares core architectural features but varies in temperature grades and packaging options. The W suffix specifically denotes the automotive qualified version designed for harsh environmental conditions.

Replacement Considerations

The AD7927BRUZ serves as the commercial grade equivalent with identical electrical specifications but a lower operating temperature limit. Verify package compatibility and pinout alignment when substituting between automotive and commercial variants.
