1. LMV321WG-7 Substitution Conclusion The LMV321WG-7 can serve as a replacement for the original part AZV321KTR-G1, but key differences must be evaluated based on the application. The primary distinctions are: a significantly lower input bias current (15 nA vs. 250 nA), which reduces error and improves accuracy in high-impedance signal chains; and a substantially lower output drive current (90 mA vs. 160 mA), which may limit performance when driving capacitive or low-impedance loads, making it unsuitable for applications requiring high output current. The two devices are fully compatible in terms of bandwidth, slew rate, supply voltage range, and package. Therefore, if the application does not demand high output current and prioritizes low input bias current, the LMV321WG-7 is the preferable choice. Conversely, if strong load-driving capability is required, the substitution is not recommended.
