AD7734BRUZ-REEL7

Overview

The AD7734BRUZ-REEL7 is a high precision, high throughput analog front end featuring a 24-bit Sigma-Delta ADC with four single-ended input channels. It supports unipolar or true bipolar input ranges up to ±10 V while operating from a single +5 V analog supply. The device offers a maximum data throughput of 15.4 kHz and includes on-chip per-channel system calibration. It features overvoltage tolerance up to ±16.5 V without affecting adjacent channels and accepts absolute maximum voltages up to ±50 V. The digital interface is compatible with SPI, MICROWIRE, and DSP protocols.

Feature Summary

• High-resolution 24-bit conversion capability with no missing codes.
• Optimized for fast channel switching suitable for multiplexing applications.
• Integrated per-channel system calibration circuitry.
• Overvoltage tolerant analog inputs protecting adjacent channels.

Applications

• Programmable Logic Controllers (PLCs)
• Distributed Control Systems (DCS)
• Multiplexing applications
• Process control systems
• Industrial instrumentation

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to tape and reel packaging when sourcing components. Confirm that the manufacturer designation matches Analog Devices Inc. to ensure authenticity. Check for RoHS compliance status as indicated in official documentation. Ensure the package type is identified as 28-lead TSSOP for proper PCB footprint compatibility.

Selection Notes

Select this component for applications requiring high accuracy with multiple single-ended inputs. Consider the chopping mode settings to balance noise performance against throughput speed. Verify that the external reference voltage meets the specified differential requirements. Ensure the microcontroller interface supports the required serial communication protocol and logic levels.

Part Context

The AD7734 belongs to a family of high-performance analog-to-digital converters from Analog Devices. Related models include the AD7732, which features two fully differential channels, and the AD7738, which offers configurable differential or single-ended inputs with lower voltage ranges. These devices share similar architectural principles but differ in channel count and input flexibility.
