AD9224ARSZRL

Overview

The AD9224ARSZRL is a monolithic, single-supply 12-bit, 40 MSPS analog-to-digital converter manufactured by Analog Devices Inc. It utilizes a multistage differential pipelined architecture with output error correction logic to ensure no missing codes across the full operating temperature range. The device integrates a high-performance sample-and-hold amplifier and voltage reference on-chip, simplifying system design. It operates from a single +5 V analog supply and supports digital driver supplies between 2.85 V and 5.25 V, allowing compatibility with 3 V or 5 V logic families. Typical power consumption ranges from 415 mW to 425 mW depending on the internal reference configuration.

Feature Summary

• Multistage differential pipelined architecture with digital error correction for guaranteed linearity
• Integrated wideband sample-and-hold amplifier supporting flexible single-ended or differential input configurations
• On-board programmable voltage reference with options for external reference integration
• Out-of-range (OTR) indicator pin for detecting signal overflow conditions

Applications

• Communications systems requiring high-speed data acquisition
• Imaging applications utilizing multiplexed channels
• Medical ultrasound equipment demanding precise signal conversion
• Test and measurement instruments needing low-noise performance

Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm that the package matches the 28-lead SSOP specification and check the date code against current production batches. Ensure proper electrostatic discharge handling protocols are followed during receipt and storage, as the device is sensitive to static charges.

Selection Notes

Select this component when a 12-bit resolution at 40 MSPS is required within a single-supply environment. Consider the integrated reference and sample-and-hold features if minimizing external component count is a priority. Evaluate the input span requirements, as the device supports both 2 Vp-p and 4 Vp-p ranges via the SENSE pin configuration. Ensure the driving source can handle the dynamic input impedance of the switched-capacitor structure.

Part Context

The AD9224 belongs to a family of high-speed CMOS analog-to-digital converters from Analog Devices. It shares pin compatibility with related models such as the AD9220, AD9221, AD9223, and AD9225, facilitating design upgrades or replacements within existing hardware architectures. This specific variant includes the 'RL' suffix indicating reel packaging for automated assembly processes.

Replacement Considerations

The AD9224 is pin-compatible with the AD9220, AD9221, AD9223, and AD9225. When substituting these parts, verify that the resolution and sampling rate requirements of the application are met by the alternative model. Check for any differences in power consumption or input specifications that might necessitate circuit adjustments.
