The TL084BCDE4: It delivers a 3 MHz gain-bandwidth product and a 13 V/µs slew rate, with a typical input bias current of 30 pA — the JFET input stage keeps bias current low enough to avoid loading high-impedance sources like photodiode transimpedance stages or pH probe buffers.
The TL084BCDE4 operates from a supply span of 10 V to 30 V. Total supply current is 1.4 mA for all four amplifiers.
It remains a current-production part suitable for new designs.
At 13 V/µs, the TL084BCDE4 can swing a 10 V peak-to-peak output at frequencies up to roughly 200 kHz before slew-rate limiting distorts the signal. For the full 3 MHz gain-bandwidth, keep output swings below about 2 V peak-to-peak to stay within the linear region.
