AD9220ARSZ

Overview

The AD9220ARSZ is a monolithic 12-bit analog-to-digital converter manufactured by Analog Devices Inc., utilizing a CMOS pipeline architecture. It operates at a maximum sampling rate of 10 MSPS with a typical power dissipation of 254 mW on a single 5 V analog supply and a digital supply range of 2.7 V to 5.25 V. The device features an integral sample-and-hold amplifier and programmable voltage reference, supporting input spans of 2 Vp-p or 5 Vp-p. Key performance metrics include a typical Signal-to-Noise and Distortion Ratio (SINAD) of 70 dB, Spurious-Free Dynamic Range (SFDR) of 86 dB, Integral Nonlinearity (INL) of ±0.5 LSB, and Differential Nonlinearity (DNL) of ±0.3 LSB. It provides straight binary output data with an Out-of-Range (OTR) indicator and exhibits a fixed pipeline latency of three clock cycles.

Feature Summary

• Monolithic 12-bit resolution with guaranteed no missing codes across the full operating temperature range.
• Integrated high-performance sample-and-hold amplifier and programmable internal voltage reference.
• Flexible differential input structure supporting both single-ended and differential configurations.
• Straight binary digital output format accompanied by an out-of-range detection signal.

Applications

• Direct IF down conversion in communication systems
• Multiplexed data acquisition systems
• Imaging and medical instrumentation

Procurement Notes

Verify the specific package variant against the ordering guide; the ARSZ suffix denotes a 28-lead SSOP package with industrial temperature range (-40°C to +85°C). Confirm that the required sampling rate aligns with the AD9220's 10 MSPS specification rather than the lower-speed family members. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS process.

Selection Notes

Select the AD9220 when a 10 MSPS throughput is required within the AD9221/AD9223/AD9220 family. Compare power consumption and dynamic performance against the AD9221 (1.5 MSPS) and AD9223 (3.0 MSPS) if lower speed suffices for the application. Consider the trade-off between full-power bandwidth and settling time when optimizing for specific input frequencies.

Part Context

The AD9220ARSZ belongs to a product family sharing identical pinouts, interface options, and packages with the AD9221 and AD9223. This pin compatibility allows designers to scale system performance up or down based on sampling rate and power requirements without redesigning the PCB layout. All family members utilize the same four-stage pipeline architecture with digital error correction logic.

Replacement Considerations

The AD9221ARSZ and AD9223ARSZ are pin-compatible alternatives within the same datasheet. Substitution requires verifying that the reduced sampling rates of 1.5 MSPS (AD9221) or 3.0 MSPS (AD9223) meet the system timing requirements.
