AD9223ARZ

Overview

The AD9223ARZ is a monolithic 12-bit analog-to-digital converter operating at a maximum sampling rate of 3.0 MSPS. It functions on a single 5 V supply with typical power dissipation of 100 mW. The device features an integral sample-and-hold amplifier and voltage reference, supporting input spans of 2 V p-p or 5 V p-p. DC accuracy includes ±0.5 LSB typical integral nonlinearity and ±0.3 LSB differential nonlinearity. AC performance provides a signal-to-noise and distortion ratio of 70 dB and a spurious-free dynamic range of 86 dB. It utilizes straight binary output data format within a 28-lead SOIC package.

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 analog input structure supporting both single-ended and differential configurations.
• Digital output error correction logic ensures accurate conversion without missing codes.

Applications

• Imaging systems
• Communications equipment
• Medical instrumentation
• Data-acquisition systems

Procurement Notes

Verify the specific suffix ARZ to confirm the 28-lead SOIC package and -40°C to +85°C industrial temperature range. Confirm that the required sampling rate aligns with the 3.0 MSPS specification, as other family members offer different speeds. Ensure the application environment supports the single 5 V supply requirement for both analog and digital domains.

Selection Notes

Select the AD9223ARZ when a 3.0 MSPS sampling rate is required, balancing the lower power consumption of the AD9221 against the higher speed of the AD9220. Consider the flexible input span options and the availability of an out-of-range indicator for system monitoring. Verify that the 12-bit resolution and 70 dB SNDR meet the dynamic performance requirements of the target application.

Part Context

The AD9223ARZ belongs to the AD9221/AD9223/AD9220 product family, which shares identical pinouts, packages, and interface options. This family allows designers to select components based on specific trade-offs between sampling rate, power dissipation, and dynamic performance while maintaining design compatibility across the series.

Replacement Considerations

The AD9221AR offers a lower sampling rate of 1.5 MSPS with reduced power consumption. The AD9220AR provides a higher sampling rate of 10.0 MSPS with increased power usage. Both are pin-compatible alternatives within the same family.
