AD7734BRUZ-REEL

Overview

The AD7734BRUZ-REEL is a high precision, high throughput analog front end featuring a 24-bit Sigma-Delta ADC with four single-ended analog inputs. It supports input ranges of ±10 V, +5 V, ±5 V, and 0 V to +10 V while operating from a single +5 V analog supply. The device offers up to 15.4 kHz data throughput 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 serial interface is compatible with SPI, QSPI, Microwire, and DSP standards.

Feature Summary

• Four single-ended analog input channels with configurable unipolar or true bipolar input ranges.
• On-chip per-channel system calibration capability for enhanced accuracy.
• Overvoltage tolerant design that protects adjacent channel performance during input excursions.
• Schmitt-triggered logic inputs for robust digital interface compatibility.

Applications

• PLCs/DCS
• Multiplexing applications
• Process control
• Industrial instrumentation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Ensure the component matches the required industrial temperature range and voltage specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component for applications requiring high-resolution multiplexing with fast channel switching times. Consider the chopping mode settings to balance noise performance against data throughput requirements. Verify that the external reference voltage and clock frequency align with the specified operational limits for optimal linearity and resolution.
