AD7934BRUZ-6REEL7

Overview

The AD7934BRUZ-6REEL7 is a 12-bit, high-speed successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It features four multiplexed analog input channels with an integrated channel sequencer and operates from a single 2.7 V to 5.25 V supply. The device achieves throughput rates up to 1.5 MSPS with low power consumption of 13.5 mW at 5 V. It includes an accurate on-chip 2.5 V reference, supports differential, pseudo-differential, and single-ended inputs, and utilizes a high-speed parallel interface compatible with 3 V or 5 V logic systems via the VDRIVE function.

Feature Summary

• Four analog input channels with software-configurable sequencing for sequential conversion.
• Integrated precise 2.5 V internal voltage reference with low temperature coefficient.
• Flexible analog input support for single-ended, fully differential, and pseudo-differential configurations.
• High-speed parallel interface with word/byte modes and independent VDRIVE logic level compatibility.

Applications

• Industrial process control systems requiring multi-channel data acquisition.
• Medical instrumentation utilizing differential signal paths.
• Battery-powered test equipment benefiting from low power operation.
• Automotive sensor interfaces requiring robust parallel communication.

Procurement Notes

Verify the specific suffix -6REEL7 against official documentation to confirm packaging and reel specifications. Ensure the ordering code matches the required tape-and-reel quantity. Cross-reference the manufacturer's current datasheet revision to validate pinout and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when 12-bit resolution and 1.5 MSPS throughput are required for multi-channel applications. Consider the AD7933 if 10-bit resolution suffices for lower cost. Evaluate the AD7938 family if eight channels are needed instead of four. Verify that the system clock frequency supports the desired sampling rate within the specified limits.

Part Context

This part belongs to the AD7933/AD7934 family of 10-bit and 12-bit SAR ADCs. It shares architectural similarities with the AD7938 series but offers fewer channels. The BRUZ suffix indicates a commercial temperature range (-40°C to +85°C) and TSSOP-28 package. The -6 variant typically denotes specific speed or configuration variants within the broader product line.

Replacement Considerations

The AD7934BRUZ is the standard tube-packaged equivalent. The AD7933BRUZ-6REEL7 serves as a 10-bit alternative. For eight-channel requirements, consider the AD7938BRUZ-6REEL7. Verify pin compatibility and software register settings when substituting these related devices.
