AD9220ARS-REEL

Overview

The AD9220ARS-REEL is a monolithic 12-bit analog-to-digital converter from Analog Devices, operating at a maximum sampling rate of 10 MSPS. It features a single 5 V analog supply and a digital supply range of 2.7 V to 5.25 V, with typical power consumption of 254 mW. The device utilizes a pipelined architecture with on-chip sample-and-hold amplifier and programmable voltage reference. Key performance metrics include an Integral Nonlinearity (INL) of ±0.5 LSB, Differential Nonlinearity (DNL) of ±0.3 LSB, Signal-to-Noise and Distortion Ratio (SINAD) of 70 dB, and Spurious-Free Dynamic Range (SFDR) of 88 dB. It offers flexible analog input spans of 2 Vp-p or 5 Vp-p and provides straight binary output data with an Out-of-Range (OTR) indicator.

Feature Summary

• Monolithic 12-bit resolution with guaranteed no missing codes across the full operating temperature range.
• Integrated high-performance sample-and-hold amplifier and programmable internal voltage reference.
• Flexible differential or single-ended analog input interface supporting AC or DC coupling.
• Straight binary digital output format accompanied by an out-of-range detection signal.

Applications

• Direct IF down conversion in communication systems
• Imaging and medical data acquisition systems
• Multiplexed sensor interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Ensure that the component matches the required industrial temperature range and pinout configuration for your design. Cross-reference the datasheet revision to validate all electrical parameters before finalizing procurement orders.

Selection Notes

Select this model when a 10 MSPS sampling rate is required alongside 12-bit linearity. Consider the trade-off between power dissipation and dynamic performance compared to lower-speed family members like the AD9221 or AD9223. Evaluate the need for external versus internal voltage references based on specific temperature drift requirements.

Part Context

This component belongs to the AD9221/AD9223/AD9220 product family, which shares identical pinouts and interface options. The family allows designers to scale performance by choosing different sampling rates while maintaining software and hardware compatibility. All members utilize the same CMOS pipelined architecture and 28-lead SSOP/SOIC packages.

Replacement Considerations

The AD9221AR and AD9223AR are pin-compatible alternatives within the same family, offering lower sampling rates of 1.5 MSPS and 3.0 MSPS respectively. These substitutes provide reduced power consumption but may exhibit different dynamic performance characteristics at higher frequencies.
