Replacement verdict
Compatible functional replacement candidate
The AD8022ARZ and AD8022AR are functionally equivalent dual high-speed voltage-feedback operational amplifiers sharing the same core die, supply range, and SOIC-8 pinout; the ARZ suffix denotes RoHS-compliant lead-free molding compound and lead finish versus the leaded AR version, making the ARZ a valid drop-in replacement in most designs subject to RoHS and solder-profile validation.

Frequently asked questions
What is the difference between AD8022ARZ and AD8022AR?
The AD8022ARZ is the RoHS-compliant, lead-free (Pb-free) version of the AD8022AR. Both are dual, high-speed, low-noise operational amplifiers in an 8-lead SOIC package from Analog Devices. The primary difference is the packaging material and compliance status: the "Z" suffix denotes RoHS compliance and lead-free construction, while the AD8022AR is the non-RoHS, lead-containing version.
Are the AD8022ARZ and AD8022AR electrically and functionally identical?
Yes. Both parts share the same die and specified electrical performance, including a 100 MHz gain bandwidth product, 120 V/µs slew rate, and low input voltage noise of 2.6 nV/√Hz. The datasheet specifications apply equally to both orderable part numbers; only the package finish and RoHS compliance differ.
Can the AD8022ARZ be used as a drop-in replacement for the AD8022AR?
Yes, in most cases. Both parts use the same 8-lead SOIC package with identical pinout and PCB land pattern, so the AD8022ARZ is a form-fit-function replacement for the AD8022AR. Designs requiring RoHS compliance should use the AD8022ARZ; the AD8022AR is not RoHS-compliant.
What are the key specifications of the AD8022ARZ and AD8022AR?
Both devices are dual voltage-feedback op amps with 100 MHz gain bandwidth, 120 V/µs slew rate, 2.6 nV/√Hz input voltage noise, and low distortion. They operate on ±5 V to ±12 V supplies and are specified for the industrial temperature range of −40 °C to +85 °C. These parameters are common to both orderable part numbers.
Is the AD8022AR still recommended for new designs?
The AD8022AR is the non-RoHS version and is generally not recommended for new designs that must meet RoHS requirements. For new designs, the AD8022ARZ (RoHS-compliant, lead-free) is the appropriate orderable part number. Designers should confirm current availability and lifecycle status with Analog Devices or an authorized distributor.
What package do the AD8022ARZ and AD8022AR use?
Both parts are supplied in an 8-lead SOIC (Small Outline Integrated Circuit) package. The package outline, pin configuration, and PCB footprint are identical between the two orderable part numbers, which is why they are interchangeable at the board level.
Do the AD8022ARZ and AD8022AR differ in temperature range or performance grades?
No. Both orderable part numbers are specified over the same industrial temperature range of −40 °C to +85 °C and share the same electrical specifications. The suffix difference (Z vs. no Z) reflects RoHS/lead-free packaging status, not a performance or temperature grade difference.
