AD977ACRS

Analog To Digital Converters (ADC) Overview

The AD977ACRS is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 5 V supply with a maximum power dissipation of 100 mW and features a throughput rate of 100 kSPS. The device utilizes a serial interface and accepts single-ended inputs within unipolar ranges of 0 V to 4 V, 0 V to 5 V, or 0 V to 10 V, as well as bipolar ranges of ±3.3 V, ±5 V, or ±10 V. It includes an internal 2.5 V reference and is housed in a 20-lead SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• Factory calibrated switched capacitor architecture minimizes linearity errors
• Single 5 V supply operation reduces system complexity
• Integrated high-speed serial interface simplifies digital connectivity

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high resolution
• Data acquisition modules for sensor interfacing
• Portable instrumentation powered by single supplies

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CRZ' against official Analog Devices documentation to confirm temperature range and packaging details. Confirm current availability status through authorized distributors as this component may have limited stock or be subject to allocation constraints due to its age.

Analog To Digital Converters (ADC) Selection Notes

Select the AD977ACRS when a 16-bit resolution and 100 kSPS sampling rate are required for single-supply applications. Ensure the input signal matches the supported unipolar or bipolar voltage ranges. Consider the AD977A variant if a higher throughput of 200 kSPS is necessary for the application.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD977 family of 16-bit ADCs from Analog Devices. It shares architectural similarities with the AD977A but offers a lower throughput rate of 100 kSPS compared to the A variant's 200 kSPS. Both variants utilize the same SAR architecture and single-supply operation.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include the AD977A series for higher speed requirements. Cross-vendor alternatives such as the ADS7809UB from Texas Instruments are listed as similar options, though pinouts and specifications should be verified against datasheets.
