Replacement verdict
Compatible functional replacement candidate
The AD8422ARZ and AD8422BRZ share the same amplifier architecture, pinout, package, and supply range, making them functionally interchangeable in most designs. The BRZ grade offers tighter gain and offset specifications, so the ARZ can serve as a drop-in substitute where the relaxed precision tolerances remain acceptable, while the BRZ is preferred for higher-accuracy signal chains.
