AD9226ARSZRL

Overview

The AD9226ARSZRL is a monolithic, single-supply, 12-bit analog-to-digital converter (ADC) 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 12-bit accuracy without missing codes across the full operating temperature range. The device features an on-chip high-performance sample-and-hold amplifier (SHA) with a full power bandwidth of 750 MHz and a programmable internal voltage reference. It accepts differential or single-ended analog inputs and provides parallel digital outputs in straight binary or two's complement formats. The component is housed in a 28-lead shrink small outline package (SSOP).

Feature Summary

• Patented on-chip sample-and-hold amplifier supporting both single-ended and differential input configurations for flexible system interfacing.
• Integrated clock duty cycle stabilizer ensures conversion immunity to varying clock pulse widths.
• Out-of-range (OTR) output bit indicates when the input signal exceeds the ADC's specified input range.
• Single 5 V analog supply operation with a separate digital driver supply accommodating 3 V or 5 V logic families.

Applications

• Intermediate Frequency (IF) undersampling schemes in communication systems.
• Imaging systems requiring high-speed data acquisition.
• Data-intensive applications demanding low power dissipation and high linearity.

Procurement Notes

Verify the specific ordering suffix ARSZRL against the manufacturer's current documentation to confirm the tape and reel packaging configuration and lead-free status. Ensure that the required ambient operating temperature range aligns with the -40°C to +85°C specification defined for this part variant. Cross-reference the pinout diagram in the official datasheet to validate compatibility with the target printed circuit board layout before finalizing procurement orders.

Selection Notes

Select this component when a 12-bit resolution at 65 MSPS is required within a compact SSOP footprint. Consider the AD9226 for designs needing a single 5 V analog supply and independent digital logic voltage options. Evaluate the internal reference capabilities against external precision requirements. Verify that the 750 MHz SHA bandwidth meets the spectral performance needs of the intended input signal frequencies.

Part Context

The AD9226 belongs to a family of high-speed monolithic ADCs from Analog Devices. It shares pin compatibility with the AD9220, AD9221, AD9223, AD9224, and AD9225 models, facilitating design upgrades or replacements within existing hardware architectures. This specific variant represents the standard commercial/industrial temperature grade version available in surface-mount packaging.

Replacement Considerations

The AD9226 is pin-compatible with the AD9220, AD9221, AD9223, AD9224, and AD9225. Designers should verify that the electrical specifications of these alternative models meet the specific performance requirements of the application before substitution.
