Overview
The AD9223ARS is a monolithic 12-bit analog-to-digital converter (ADC) from Analog Devices, operating at a maximum sampling rate of 3.0 MSPS. It utilizes a multistage differential pipelined architecture with digital output error correction logic to ensure true 12-bit linearity and guarantee no missing codes across the full operating temperature range. The device features an on-chip sample-and-hold amplifier and a programmable voltage reference, supporting both single-ended and differential input configurations. It operates on a single 5 V analog supply and accepts digital supplies between 2.7 V and 5.25 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70 dB, Integral Nonlinearity (INL) of ±1.25 LSB max, and Differential Nonlinearity (DNL) of ±0.75 LSB max. Power consumption is typically 100 mW.
Feature Summary
- Monolithic 12-bit resolution with guaranteed no missing codes over the operating temperature range.
- Flexible analog input structure supporting both single-ended and differential interfaces with varying input spans.
- Integrated high-performance sample-and-hold amplifier and programmable internal voltage reference.
- Straight binary output data format with an out-of-range indicator for overflow detection.
Applications
- Imaging systems requiring high-speed digitization.
- Communications systems employing Direct-IF down conversion.
- Medical instrumentation and data-acquisition systems.
Procurement Notes
Verify the specific ordering suffix 'RS' confirms the 28-lead SSOP package variant. Confirm the temperature range matches the -40°C to +85°C specification. Check RoHS compliance status as indicated in the manufacturer's documentation. Ensure the component source is authorized to avoid counterfeit parts, especially given the age of the product family.
Selection Notes
Select the AD9223ARS when a 3.0 MSPS sampling rate is required within the AD922x family. Compare against AD9221AR for lower power applications at 1.5 MSPS or AD9220AR for higher speed at 10.0 MSPS. All members share identical pinouts and interface options, allowing for flexible system design adjustments based on dynamic performance and power constraints without redesigning the PCB layout.
Part Context
The AD9223ARS belongs to the AD9221/AD9223/AD9220 product family, which shares a common CMOS pipelined architecture. These devices are designed to offer upward or downward selection paths based on sampling rate and power dissipation. The family provides pin-compatible solutions in 28-lead SOIC and SSOP packages, simplifying upgrades or downgrades in existing designs while maintaining interface compatibility.
Replacement Considerations
The AD9221AR and AD9220AR are direct pin-compatible substitutes within the same family, differing only in specified sampling rates (1.5 MSPS and 10.0 MSPS respectively) and power consumption. Verify that the alternative part's dynamic performance meets the application requirements at the desired clock frequency.
