Product details

13V/µs slew rate — what it buys the signal chain

The TL084BCD is a JFET-input quad operational amplifier from Texas Instruments. Its 13V/µs slew rate and 3 MHz gain-bandwidth product give it enough dynamic range for audio preamplifiers, active filters, and fast-settling signal conditioning stages where a general-purpose 741 or LM358 would round off the waveform.

Quad channel density in a 14-SOIC footprint

Four independent amplifiers in a single 14-SOIC package — that is four gain stages on the board area of two single-channel SOIC-8s. Total quiescent current for all four amplifiers is 1.4 mA, which keeps the thermal rise low in the SOIC package.

Temperature grade and deployment scope

That covers benchtop instruments, studio audio gear, office-environment industrial controls, and consumer electronics. For automotive or outdoor telecom enclosures, look at the industrial-grade TL084 variants.

Frequently asked questions

What is the gain bandwidth product of TL084BCD?

The TL084BCD has a gain-bandwidth product of 3 MHz. That sets the closed-loop bandwidth at a gain of 10 to about 300 kHz, which is adequate for audio-band active filters and many sensor-conditioning loops.

What is the slew rate of TL084BCD?

The slew rate is 13V/µs. That means a 10 V peak-to-peak output swing can change at about 0.77 V/µs per volt — enough to reproduce a 20 kHz sine wave at full amplitude without slew-induced distortion.

Can I use TL084BCD instead of TL084CD?

The TL084BCD and TL084CD share the same JFET quad op-amp core, the same 3 MHz GBW and 13V/µs slew rate, and the same 14-SOIC footprint. Functionally they are interchangeable — check your BOM for the exact ordering code and packaging preference.

Can TL084BCD be used in audio circuits?

Yes. The 13V/µs slew rate and 3 MHz GBW are well within the requirements for line-level audio preamplifiers, active tone controls, and headphone drivers. The JFET input stage also gives low noise at high source impedances typical of guitar pickups and microphone preamps.
