Thank you for understanding

Context: The AD9220 / AD9221 / AD9223 ADC Family

• The AD9220, AD9221, and AD9223 are part of a high-performance, single-supply, 12-bit pipelined ADC family with identical interfaces and pinouts. This allows designers to interchange parts based on sampling rate or power constraints:

  • AD9220 — Up to 10 MSPS, 250 mW

  • AD9223 — Up to 3 MSPS, 100 mW

  • AD9221 — Up to 1.5 MSPS, 59 mW

• They support both single-ended and differential input modes, feature low noise and high dynamic performance, and come in 28-lead SOIC or SSOP packages.

• The AD9220-EB is an evaluation board intended for testing and evaluating the AD9220, a 12-bit, 1.5 MSPS (mega-samples per second) ADC. It provides designers with a ready-to-use platform to assess performance, interface, and integration ease.

• Analog Devices lists evaluation and development boards in their “Evaluation Hardware and Software” section, which includes boards for ADC evaluation. While the AD9220-EB board appears in this family, there’s no direct mention of evaluation boards specifically for the AD9221 or AD9223.

Key Features of the AD9220-EB

• Designed specifically for evaluating the AD9220, a 12-bit monolithic ADC with integrated sample-and-hold and flexible input options.

• It typically includes standard ADC evaluation features such as differential input support, reference source selection, and output interface, streamlining performance testing in lab environments.

• The board is often paired with data capture solutions (e.g., USB FIFO or FPGA-based carriers) to facilitate signal capture and analysis.
