AD9220ARSZ-REEL

Overview

The AD9220ARSZ-REEL is a monolithic 12-bit analog-to-digital converter from Analog Devices Inc., operating at a maximum sampling rate of 10 MSPS. It utilizes a multistage differential pipelined architecture with digital output error correction logic to ensure true 12-bit linearity and guarantee no missing codes across the full operating temperature range. The device features an on-chip sample-and-hold amplifier and a programmable voltage reference, supporting input spans of 2 Vp-p or 5 Vp-p. It operates on a single 5 V analog supply and a 2.7 V to 5.25 V digital supply, consuming approximately 254 mW. Key performance metrics include a typical SINAD of 70 dB, SFDR of 88 dB, and a full power bandwidth of 60 MHz.

Feature Summary

• Integrated high-performance sample-and-hold amplifier and programmable voltage reference for simplified system design
• Flexible analog input structure supporting both single-ended and differential configurations with AC or DC coupling
• Multistage differential pipelined architecture with digital correction logic ensuring accurate 12-bit resolution
• Out-of-range (OTR) indicator signal to detect overflow conditions alongside straight binary data output

Applications

• Direct IF down conversion in communication systems
• Imaging and medical data acquisition systems
• Multiplexed systems requiring switching between full-scale voltage levels
• High-speed data acquisition applications

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. Ensure the component matches the required sampling rate specifications for your application. Check for ESD sensitivity precautions during handling. Confirm that the voltage supply requirements align with your system's power rails. Validate the pinout compatibility if replacing existing components.

Selection Notes

Select this model when a 10 MSPS sampling rate is required within the AD922x family. Consider the AD9223 or AD9221 if lower power consumption or reduced sampling rates better suit the application constraints. Evaluate the trade-off between power dissipation and dynamic performance characteristics. Ensure the interface logic levels are compatible with the available digital supply voltage options.

Part Context

This component belongs to the AD9221/AD9223/AD9220 product family, which shares identical pinouts, packages, and interface options. The family allows for upward or downward selection based on specific performance needs regarding speed and power. All members utilize the same CMOS pipelined architecture and offer flexible input configurations.

Replacement Considerations

The AD9221ARSZ-REEL and AD9223ARSZ-REEL are pin-compatible alternatives within the same family. These substitutes offer different specified sampling rates and power consumption profiles while maintaining identical physical interfaces.
