AD7934BRUZ-6

Overview

The AD7934BRUZ-6 is a 12-bit, high-speed, low-power successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It features four analog input channels with 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 1.5 MSPS with a differential signal-to-noise ratio of 70 dB minimum at 50 kHz input frequency. It includes an accurate on-chip 2.5 V reference source and accepts single-ended, fully differential, or pseudo-differential inputs. The parallel interface allows direct connection to 3 V or 5 V processor systems via the VDRIVE function.

Feature Summary

• Four analog input channels with software-configurable sequencer for sequential conversion.
• Integrated precise 2.5 V internal voltage reference with low temperature coefficient.
• Flexible analog input configuration supporting single-ended, fully differential, and pseudo-differential modes.
• High-speed parallel interface with word/byte transfer modes and independent logic drive voltage.

Applications

• Industrial process control data acquisition systems
• Portable instrumentation requiring low power consumption
• Battery-powered measurement devices
• Vibration monitoring and acoustic sensing applications

Procurement Notes

Verify the specific suffix -6 against the official datasheet ordering guide to confirm performance grade and package variant. Ensure compatibility with system voltage levels and interface requirements before procurement. Cross-reference manufacturer part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when 12-bit resolution and multi-channel sequencing are required in a compact surface-mount package. Compare power dissipation specifications against thermal constraints in the final enclosure. Evaluate the need for external versus internal reference sources based on system accuracy requirements.

Part Context

This device belongs to the AD7933/AD7934 family of parallel ADCs. It shares architectural similarities with the AD7938 series but offers fewer channels. The -6 suffix typically denotes a specific performance bin or package option within the broader AD7934 product line defined by Analog Devices.

Replacement Considerations

The AD7934BRUZ is the standard version of this component with identical pinout and functionality. Verify if the -6 suffix indicates a specific testing grade or packaging variation that requires exact matching in production environments.
