Overview
The AD9221AR-REEL is a monolithic 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a pipeline architecture with an integrated sampling hold amplifier and programmable reference source, supporting maximum sampling rates of 1.5 MSPS. The device operates on a single +5V analog supply and accepts digital logic voltages between 2.7V and 5.25V. Key electrical specifications include a typical power dissipation of 59mW, an input-referred noise of 0.09 LSB rms at VREF=2.5V, and a full-power bandwidth of 25MHz. It provides parallel straight binary output data with a fixed three-clock-cycle latency.
Feature Summary
- 12-bit resolution with 1.5 MSPS maximum sampling rate in a pipeline architecture
- Single +5V analog supply operation with low power consumption of 59mW typical
- Integrated sampling hold amplifier and programmable internal voltage references (1V or 2.5V)
- Supports both differential and single-ended input configurations
Applications
- Imaging systems requiring high-speed digitization
- Industrial process control and data acquisition
- Medical instrumentation and ultrasound imaging
- Communications equipment signal processing
Procurement Notes
Verify the specific suffix 'REEL' against official Analog Devices documentation to confirm tape-and-reel packaging availability for this exact part number. Cross-reference with the AD9221ARSZ-REEL variant if reel packaging is required, as standard tube packages may differ. Confirm end-of-life status and discontinuation notifications prior to procurement planning.
Selection Notes
Select this component when a 12-bit resolution and 1.5 MSPS throughput are sufficient for the application. Ensure the system design accommodates the 28-pin SOIC package for the 'AR' suffix. Verify that the digital interface logic levels match the 2.7V to 5.25V DVDD range. Consider thermal management requirements given the 59mW typical power dissipation.
Part Context
The AD9221 belongs to the AD922x family of high-speed, low-power monolithic ADCs from Analog Devices. This family includes variants such as the AD9220 (10 MSPS), AD9221 (1.5 MSPS), and AD9223 (3 MSPS). These devices share similar pinouts and architectural features, facilitating design scalability across different speed requirements within industrial and communication applications.
Replacement Considerations
Publicly confirmed substitute part numbers for the AD9221AR-REEL were not identified in the provided source material. Consult Analog Devices technical support for current obsolescence notices and recommended alternative components.
