AD9223ARZ-REEL

Overview

The AD9223ARZ-REEL is a monolithic 12-bit analog-to-digital converter operating at a maximum sampling rate of 3.0 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 100 mW. The device incorporates an on-chip sample-and-hold amplifier and a programmable voltage reference supporting 1 V or 2.5 V modes. Key performance metrics include a typical Signal-to-Noise and Distortion Ratio (SINAD) of 70 dB, Spurious-Free Dynamic Range (SFDR) of 86 dB, Integral Nonlinearity (INL) of ±0.5 LSB, and Differential Nonlinearity (DNL) of ±0.3 LSB. It utilizes a pipelined architecture with straight binary output and an out-of-range 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 input structure supporting both single-ended and differential configurations.
• Straight binary digital output format with an out-of-range (OTR) overflow detection signal.

Applications

• Imaging systems requiring moderate speed data acquisition
• Communications equipment utilizing direct IF down conversion
• Medical instrumentation for signal digitization
• General-purpose data-acquisition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature rating. Confirm that the REEL designation matches the required tape and reel specifications for automated assembly processes. Cross-reference the component marking with official datasheets to validate authenticity and revision level prior to integration into production designs.

Selection Notes

Select this model when a 3.0 MSPS sampling rate is required within the AD922x family. Compare power dissipation and dynamic performance against the AD9221 (1.5 MSPS) and AD9220 (10.0 MSPS) variants to optimize system efficiency. Ensure the analog input common-mode voltage and span requirements align with the flexible SHA capabilities described in the application guidelines.

Part Context

This component belongs to the AD9221/AD9223/AD9220 product family, which shares identical pinouts, packages, and interface options. The family allows designers to scale performance by selecting different sampling rates while maintaining design compatibility. The AD9223 specifically bridges the gap between the lower-speed AD9221 and the higher-speed AD9220 in terms of throughput and power consumption.

Replacement Considerations

The AD9221AR and AD9220AR are pin-compatible alternatives within the same family, offering 1.5 MSPS and 10.0 MSPS speeds respectively. Verify that the dynamic performance differences at the target input frequency meet system requirements before substituting.
