AD9226ARSRL

Overview

The AD9226ARSRL is a monolithic, single-supply, 12-bit analog-to-digital converter manufactured by Analog Devices Inc. It operates at a maximum sampling rate of 65 MSPS and utilizes a multistage differential pipelined architecture with output error correction logic to ensure accuracy across the full operating temperature range. The device features an on-chip high-performance sample-and-hold amplifier and voltage reference, supporting both straight binary and two's complement data formats. It accepts differential or single-ended analog inputs and includes an out-of-range (OTR) indicator. The component is designed for low power dissipation, consuming approximately 475 mW under standard test conditions.

Feature Summary

• Patented on-chip sample-and-hold amplifier providing a full power bandwidth of 750 MHz for effective IF undersampling applications.
• Integrated clock duty cycle stabilizer that makes conversion immune to varying clock pulse widths.
• Programmable internal voltage reference with options for external reference selection via the SENSE pin.
• Guaranteed no missing codes over the full operating temperature range with low differential and integral nonlinearity errors.

Applications

• Single-channel communication systems utilizing IF undersampling schemes
• Imaging systems requiring high-speed data acquisition
• Direct intermediate frequency (IF) conversion to digital domains

Procurement Notes

Verify the specific ordering suffix RL against the manufacturer's official documentation to confirm reel packaging specifications and tape dimensions. Ensure the selected variant matches the required package type, as the base model supports multiple form factors. Cross-reference the revision level with the latest datasheet to confirm pin compatibility and electrical characteristics remain unchanged.

Selection Notes

Select this component when a balance of 12-bit resolution and 65 MSPS speed is required for mid-frequency signal processing. Consider the single 5 V analog supply and separate 3 V/5 V driver supply for simplified power design. Evaluate the pipeline latency of seven clock cycles against system timing requirements. Verify input span compatibility with the available reference voltage options.

Part Context

The AD9226 belongs to a family of high-speed ADCs from Analog Devices, including the AD9220, AD9221, AD9223, AD9224, and AD9225. These devices share pin compatibility and architectural similarities, allowing for design flexibility across different resolution and speed requirements within the same product line. The AD9226 specifically targets applications needing 12-bit performance at 65 MSPS.

Replacement Considerations

Pin-compatible alternatives include the AD9220, AD9221, AD9223, AD9224, and AD9225. Verify that the substitute part meets the specific resolution and sampling rate requirements of the application before substitution.
