Replacement verdict
Compatible functional replacement candidate
The AD8022ARMZ and AD8022ARM are functionally equivalent dual high-speed voltage-feedback operational amplifiers from Analog Devices, sharing the same core die, supply range, bandwidth, and pinout. The only material distinction is the package finish: the AD8022ARMZ is RoHS-compliant lead-free (Z suffix), while the AD8022ARM is the non-RoHS leaded version. For RoHS-restricted assemblies, the AD8022ARMZ is the preferred drop-in choice; the AD8022ARM should be reserved for legacy or exempt applications.

Key electrical and mechanical differences between the two devices
| Parameter | AD8022ARMZ | AD8022ARM | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 2 | Both are dual op-amps, so channel count matches for direct circuit substitution. |
| Supply Voltage Range | ±2.5 V to ±12 V (5 V to 24 V total) | ±2.5 V to ±12 V (5 V to 24 V total) | Identical supply range ensures the part can drop into the same power rail design. |
| -3 dB Bandwidth | 100 MHz | 100 MHz | Matching bandwidth preserves AC signal fidelity and frequency response in the application. |
| Slew Rate | 100 V/µs | 100 V/µs | Equal slew rate maintains large-signal transient performance and stability. |
| Input Offset Voltage (max) | 1.5 mV | 1.5 mV | Same offset spec ensures comparable DC accuracy in precision signal chains. |
| Input Voltage Noise | 2.7 nV/√Hz | 2.7 nV/√Hz | Identical noise density keeps low-noise performance unchanged in sensitive front-ends. |
| Quiescent Current per Amplifier | 4 mA | 4 mA | Same supply current means no change to power budget or thermal design. |
| Package / Mounting | 8-Lead MSOP, Surface Mount | 8-Lead MSOP, Surface Mount | Identical package and footprint allow direct PCB replacement without layout changes. |
| RoHS / Lead-Free Status | RoHS Compliant, Lead-Free | Non-RoHS (contains lead) | The Z suffix denotes lead-free/RoHS compliance, which affects regulatory and manufacturing requirements. |
