Dual J-FET op-amp in 8-SOIC — last-buy status drives the sourcing decision
The TL082ACDG4 is a dual J-FET input operational amplifier from Texas Instruments, offering a 3 MHz gain bandwidth product and a 13V/µs slew rate. It operates from a 10 V to 30 V supply span and draws 1.4 mA per channel. The 8-SOIC package suits surface-mount assembly on mixed-signal boards where low input bias current (30 pA) and moderate speed are needed — think audio preamps, active filters, or signal conditioning in bench instruments and office equipment.
The 13V/µs slew rate supports full-power bandwidth up to roughly 200 kHz at 10 V output swing — enough for audio-band signals and control-loop filtering without slew-induced distortion. The 3 MHz gain-bandwidth product means the open-loop gain drops to unity at 3 MHz; for a gain-of-10 stage, expect a closed-loop bandwidth around 300 kHz. The 30 pA input bias current is typical for J-FET inputs, keeping DC errors low in high-impedance sensor interfaces.
This is not an active-production part; once the last-buy date passes, availability shifts to surplus and broker channels.
