Replacement verdict
Compatible functional replacement candidate
The AD9200ARSZ is a RoHS-compliant, lead-free version of the AD9200ARS and is functionally interchangeable in the same SSOP-28 package with identical 10-bit resolution, 20 MSPS sampling rate, and 2.7 V to 5.5 V supply range. The only meaningful distinction is package finish and environmental compliance, so the AD9200ARSZ can serve as a direct drop-in replacement where RoHS compliance is required.

Key electrical and mechanical differences between the two devices
| Parameter | AD9200ARSZ | AD9200ARS | Why it matters |
|---|---|---|---|
| Resolution | 10 bit | 10 bit | Determines the quantization precision of the ADC; identical resolution means equivalent signal-to-noise performance for a given input. |
| Sampling Rate | 20 MSPS | 20 MSPS | Sets the maximum input bandwidth the converter can digitize; matching rates ensure the same throughput capability. |
| Number of Input Channels | 1 | 1 | Defines whether the device is single or multi-channel; both being single-channel confirms the same system architecture. |
| Supply Voltage (Analog) | 3 V | 3 V | Must match the board's analog rail; identical supply voltage allows direct drop-in replacement without power redesign. |
| Supply Voltage (Digital) | 3 V | 3 V | Determines logic-level compatibility with downstream digital circuitry; matching values preserve interface integrity. |
| Input Type | Differential | Differential | Affects the analog front-end design; both being differential means the same input conditioning network can be reused. |
| Package / Case | 28-SSOP | 28-SSOP | Footprint and pinout must match for physical interchangeability; identical package ensures the same PCB land pattern works. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Defines the environmental envelope for reliable operation; matching ranges confirm suitability for the same application conditions. |
| RoHS / Lead-Free Status | RoHS compliant, lead-free | Contains lead (non-RoHS) | The "Z" suffix denotes lead-free/RoHS compliance; this affects regulatory compliance and solder process selection, making the parts non-interchangeable for RoHS-restricted designs. |

Frequently asked questions
What is the difference between AD9200ARSZ and AD9200ARS?
The AD9200ARSZ is the RoHS-compliant, lead-free (Pb-free) version of the AD9200ARS. Both are 10-bit, 20 MSPS analog-to-digital converters in a 28-lead SSOP package. The "Z" suffix in AD9200ARSZ denotes the lead-free/RoHS-compliant package variant, while AD9200ARS is the older lead-containing (Pb-Sn) package version. Functionally and electrically, they are the same device.
Are AD9200ARSZ and AD9200ARS electrically and functionally interchangeable?
Yes. Both parts share the same die, specifications, and pinout. The AD9200 is a 10-bit, 20 MSPS ADC with an on-chip sample-and-hold amplifier and voltage reference, operating from a single 2.7 V to 5.5 V supply. The only difference is the package finish (lead-free vs. leaded), so they are functionally interchangeable in designs that accept either finish.
What are the key specifications of the AD9200?
The AD9200 is a 10-bit monolithic CMOS ADC with a maximum sampling rate of 20 MSPS. It features a 28-lead SSOP package, on-chip sample-and-hold, an internal voltage reference, and operates from a single 2.7 V to 5.5 V supply. It offers low power consumption and is suitable for applications such as imaging, video, and communications. Verify exact dynamic performance (SNR, SFDR) against the official Analog Devices datasheet for your grade.
Is the AD9200ARSZ RoHS compliant while the AD9200ARS is not?
Yes. The "Z" suffix in AD9200ARSZ indicates RoHS compliance and a lead-free (Pb-free) package finish, per Analog Devices' part-numbering convention. The AD9200ARS uses a lead-containing finish and is not RoHS compliant. Designs requiring RoHS compliance should specify AD9200ARSZ.
Can I substitute AD9200ARSZ for AD9200ARS in an existing design?
Yes, in most cases. Because both share the same die, pinout, and electrical specifications, AD9200ARSZ can replace AD9200ARS. The substitution is appropriate when the assembly process and regulatory requirements accept lead-free (RoHS) components. Confirm solder profile compatibility with your manufacturing process, since the lead-free finish may require a higher reflow temperature.
Do AD9200ARSZ and AD9200ARS use the same package and pinout?
Yes. Both are offered in the same 28-lead SSOP (Shrink Small Outline Package) with identical pin assignments. The package body and PCB land pattern are the same, so no layout change is required when switching between the two variants.
Which part number should I order for a new RoHS-compliant design?
Order AD9200ARSZ. It is the RoHS-compliant, lead-free variant of the AD9200 and is the appropriate choice for new designs requiring compliance with RoHS directives. The AD9200ARS (leaded) variant is generally intended for legacy or non-RoHS applications.
