2. LM358ADR2G Substitution Conclusion This device is generally acceptable as a substitute, but two important limitations must be considered: one key weakness and one performance downgrade. The LM358ADR2G (onsemi) offers a slightly wider supply voltage range (max. 32V) and comparable output current capability, with input offset voltage similar to the ST version (2 mV). The most significant unknown/weakness is its unspecified slew rate, which introduces considerable risk—its large-signal response may be slower, potentially causing issues in applications requiring fast step response. Verification through testing in the actual circuit is essential before substitution. Another downgrade is its notably higher input bias current (45 vs. 20 nA). When used with high-value feedback or input resistors, this will generate larger offset voltage errors, making it less suitable for precision applications such as high-impedance sensing. If the target circuit is not sensitive to slew rate and input bias current, this device can be substituted; otherwise, careful evaluation is advised.
