AD7723BSZ-REEL

Overview

The AD7723BSZ-REEL is a 16-bit, 1.2 MSPS CMOS Sigma-Delta Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. It operates from a single 5 V supply and features an on-chip 2.5 V voltage reference. The device provides flexible parallel or serial interfaces and includes a crystal oscillator. Key specifications include a signal-to-noise ratio of up to 91 dB with a 3 V reference, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±2 LSB. It supports both unipolar and bipolar input modes and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated digital filter with low-pass and band-pass response options
• On-chip 2.5 V voltage reference with external reference capability
• Flexible data interface supporting both parallel and serial formats
• Stereo mode for sharing a single serial data line between two devices

Applications

• High-speed data acquisition systems requiring 16-bit resolution
• Industrial process control applications
• Audio processing equipment
• Medical instrumentation

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging rather than tray packaging when sourcing. Confirm the B version designation matches the required performance specifications. Ensure the component meets RoHS compliance standards for your region. Check for moisture sensitivity levels prior to soldering. Validate that the supplier provides original manufacturer documentation.

Selection Notes

Select this component when a high-speed 16-bit ADC with integrated filtering is required. Consider the decimation ratio settings for desired output data rates. Evaluate the power consumption requirements against the standby mode capabilities. Ensure the clock frequency aligns with the specified maximum limits for the selected power mode.

Part Context

This part belongs to the AD7723 series of sigma-delta ADCs. It is designed for applications demanding high accuracy and speed. The BSZ suffix denotes the specific package type and lead-free status. It serves as a complete solution by integrating the modulator, digital filter, and reference.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify if newer revisions offer improved dynamic performance. Ensure substitute parts support the same interface protocols and voltage levels.
