The ADA4077-2ARZ-R7 is a strong functional alternative. It matches the package, pinout, supply voltage, and bandwidth, but has a lower slew rate and higher input bias current, which must be verified for your application.
Best Alternatives to TL082IDR
TL082IDR is a popular dual JFET-input operational amplifier from Texas Instruments, known for its low input bias current. Finding a replacement requires careful matching of electrical characteristics, especially input type and slew rate.
AI replacement insight
Electrical riskhigh
Input bias current, slew rate, and bandwidth differences require circuit analysis.
Package risklow
Many candidates are available in the same SOIC-8 package with a standard pinout.
Firmware risklow
Not applicable for this type of component.
Can it be replaced directly?
No direct, drop-in replacement exists without caveats. The most critical difference in candidates is the input stage (JFET vs. Bipolar/CMOS), which significantly impacts input bias current.
Best replacement path
For high-impedance circuits, find another dual JFET op-amp. Otherwise, a CMOS-input op-amp with low bias current is the next best choice. Bipolar-input amps like ADA4077-2ARZ-R7 can work if higher input current is acceptable.
Main risk
The primary risk is mismatching the input bias current. The target's JFET input is crucial for high-impedance circuits; a bipolar replacement could cause significant DC errors.
