AD976ARZ

Analog To Digital Converters (ADC) Overview

The AD976ARZ is a high-speed, low-power 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 5 V supply and features a successive approximation register (SAR) architecture with a switched capacitor input stage. The device offers a throughput of 200 kSPS and includes an internal 2.5 V reference. It utilizes a high-speed parallel interface and accepts an analog full-scale input range of ±10 V. Factory calibration minimizes linearity errors, ensuring high accuracy. The component is housed in a 28-lead SSOP package and is designed for applications requiring precise data acquisition with minimal power consumption.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit SAR ADC with a switched capacitor front-end for high-speed conversion.
• Includes an on-chip 2.5 V voltage reference to simplify system design.
• Features factory calibration to minimize integral and differential nonlinearity errors.
• Supports single 5 V supply operation with low power dissipation.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition.
• Medical instrumentation such as ultrasound and patient monitoring devices.
• Test and measurement equipment needing accurate analog signal digitization.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RZ' indicates RoHS compliance and lead-free status according to Analog Devices documentation. Confirm package type is SSOP-28. Check current lifecycle status as older ADC models may be discontinued or subject to limited availability. Ensure supply chain sources provide valid manufacturer traceability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 200 kSPS sampling rate are required within a single 5 V supply constraint. Compare against the AD976A if lower throughput is acceptable. Consider the AD976ARZ for designs prioritizing integrated reference and calibration over external component count. Verify input voltage range compatibility with the ±10 V specification.

Analog To Digital Converters (ADC) Part Context

The AD976ARZ belongs to the AD976 family of 16-bit BiCMOS A/D converters. This series is characterized by its combination of speed, resolution, and low power consumption. The 'ARZ' designation typically denotes the RoHS-compliant version in the SSOP package. It serves as a bridge between general-purpose ADCs and specialized high-speed converters in industrial applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may include other variants within the AD976 family, such as the AD976ANZ for DIP packaging. Verify electrical specifications match exactly, particularly the 200 kSPS throughput and ±10 V input range. Cross-reference with newer Analog Devices ADC families for improved performance if available.
