AD7714AN-5

Analog To Digital Converters (ADC) Overview

The AD7714AN-5 is a complete analog front end for low-frequency measurement applications, featuring a charge balancing ADC with 24-bit no missing codes performance. It operates from a single +5 V supply and accepts low-level signals directly from transducers. The device includes a five-channel programmable gain front end with gains ranging from 1 to 128. It supports three fully differential or five pseudo-differential inputs and utilizes a sigma-delta conversion technique. The part features a three-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a five-channel programmable gain front end capable of accepting direct transducer signals without external conditioning.
• Provides configurable input modes supporting either three fully differential or five pseudo-differential analog channels.
• Includes on-chip self-calibration and system calibration options to eliminate endpoint errors and temperature drift effects.
• Features a low-pass digital filter with programmable cutoff frequencies to adjust settling time and noise rejection.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure that the required supply voltage matches the -5 designation for 5 V operation. Confirm availability status as older revisions may be subject to discontinuation notices.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 5 V single-supply operation is required for multi-channel signal conditioning. Consider the AD7714Y grade if an extended temperature range up to 105°C or lower power consumption is necessary. Verify that the serial interface timing requirements align with the host microcontroller or DSP capabilities.

Analog To Digital Converters (ADC) Part Context

This device belongs to the AD7714 family of signal conditioning ADCs designed for precision measurement. It serves as a comprehensive solution for integrating sensor interfaces in embedded systems. The family includes variants for 3 V operation and different package styles such as SOIC and SSOP to accommodate various board layout constraints.

Analog To Digital Converters (ADC) Replacement Considerations

The AD7714YN offers equivalent functionality with an extended temperature range and lower power consumption. For 3 V operation, the AD7714AN-3 provides similar specifications within the standard temperature range. Evaluate these alternatives based on thermal requirements and supply voltage constraints.
