AD7714ARS-5REEL

Overview

The AD7714ARS-5REEL is a 24-bit sigma-delta analog-to-digital converter (ADC) from Analog Devices, packaged in a 28-lead shrink small outline package (SSOP). It operates on a single +5 V supply and features five programmable gain channels with gains ranging from 1 to 128. The device integrates a low-pass digital filter with programmable cutoff frequencies and supports serial interfaces including SPI, QSPI, Microwire, and DSP modes. It provides self-calibration capabilities and offers high accuracy with integral nonlinearity of -0.0015% of FSR.

Feature Summary

• Integrates a complete analog front end with a charge balancing ADC and programmable gain amplifier for direct transducer interfacing.
• Features a digital filter with programmable notch frequencies to reject power line interference at 50 Hz or 60 Hz.
• Supports multiple serial communication protocols including three-wire operation to minimize interconnect lines.
• Includes on-chip calibration registers allowing users to read and write calibration coefficients for system accuracy.

Applications

• Portable industrial instruments
• Portable weigh scales
• Loop-powered systems
• Pressure transducers

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and voltage rating. Ensure the REEL designation matches the required tape-and-reel packaging format for automated assembly processes. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status.

Selection Notes

Select this component when a 24-bit resolution with integrated signal conditioning is required for low-frequency measurements. The SSOP package is suitable for space-constrained designs compared to larger DIP or SOIC options. Consider the Y-grade variants if an extended temperature range up to +105°C or lower power consumption is necessary for the application environment.

Part Context

This model belongs to the AD7714 family of signal conditioning ADCs designed for precision measurement applications. The 'ARS' suffix specifically denotes the 28-lead shrink small outline package variant operating at 5 V. The series is engineered for microcontroller-based systems requiring high accuracy and minimal external components.

Replacement Considerations

Direct replacements within the same package and specification include other AD7714 variants such as the AD7714AR-5 or AD7714YN. For upgraded performance with lower power and wider temperature ranges, consider the AD7714YRUZ or AD7714YRZ models which offer similar functionality in different packages.
