AD9220AR Equivalent & Substitute Parts

Part Overview

The AD9220AR is a 12-bit pipelined analog-to-digital converter manufactured by Analog Devices Inc., designed for data acquisition applications requiring single or differential input processing. This component operates at a 10 MHz sampling rate with parallel data interface output and supports both external and internal voltage references. The part is currently in active production status with ROHS3 compliance and is available in 28-SOIC surface mount packaging. Substitute parts are identified when electrical specifications, mechanical compatibility, and regulatory certifications remain equivalent across the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD9220AR is determined by equivalence across the following critical parameters: 12-bit resolution, 10 MHz sampling rate, single input channel, differential and single-ended input capability, parallel data interface, pipelined architecture, external and internal reference support, 5V analog supply, 2.7V–5.25V digital supply range, -40°C to 85°C operating temperature, 28-SOIC package geometry, surface mount configuration, ROHS3 compliance, and MSL 3 rating. Parts meeting all these specifications are classified as direct substitutes within the AD9220 product family.

Parameter Comparison

Engineering Selection Recommendations

Both AD9220AR and AD9220ARZ are active production components from Analog Devices Inc. with identical electrical specifications, mechanical packaging, and regulatory compliance. Selection between these parts is based on availability and supply chain requirements. Both parts maintain ROHS3 compliance and MSL 3 rating, ensuring compatibility with standard manufacturing and storage protocols. The AD9220ARZ variant currently maintains higher inventory availability at 2888 pieces compared to 1414 pieces for the AD9220AR, which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are AD9220AR and AD9220ARZ electrically interchangeable? A: Yes. Both parts share identical 12-bit resolution, 10 MHz sampling rate, input configuration, supply voltage specifications, temperature range, and reference type capabilities. They are direct electrical equivalents.

Q: Can these parts be used interchangeably in PCB designs? A: Yes. Both components use the 28-SOIC surface mount package with identical pin configuration and mechanical dimensions (0.295", 7.50mm width). No PCB layout modifications are required for substitution.

Q: What is the difference between AD9220AR and AD9220ARZ? A: The parts are functionally and mechanically identical. The suffix variation (R vs. RZ) indicates different packaging or distribution channels from Analog Devices Inc., but electrical performance and compliance certifications remain equivalent.

Q: Are both parts RoHS compliant? A: Yes. Both AD9220AR and AD9220ARZ are ROHS3 compliant and carry MSL 3 moisture sensitivity rating with 168-hour storage limits at specified conditions.

Q: Which part should be selected for new designs? A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times, as both maintain active production status and identical specifications.
