Product details

Each channel draws 1.4 mA supply current, making it a fit for multi-channel signal conditioning where power per channel matters. The AEC-Q100 qualification signals it was characterised for automotive-grade reliability, though the 0°C~70°C commercial temperature range limits deployment to cabin or indoor environments — not under-hood.

A 16 V/µs slew rate means this op-amp can swing a 10 V peak-to-peak output at roughly 250 kHz without slewing into distortion. For audio line-level signals or sensor outputs below 100 kHz, the slew rate is generous; for higher-speed ADC drivers or video buffers, it runs out of steam. The 40 mA output current per channel can drive a modest load — think 600 Ω headphones or a 10-bit SAR ADC input — without an external buffer.

JFET input — 20 pA bias current, 3 mV offset

That matters when the source impedance is high, like a photodiode or a pH probe. The 3 mV input offset voltage is typical for a general-purpose JFET part; if your application needs sub-mV precision, you would reach for an auto-zero or precision bipolar amplifier instead.

Frequently asked questions

Is TL084ACD obsolete?

Yes, the TL084ACD carries an Obsolete lifecycle status. It is no longer manufactured by Texas Instruments.

What is the equivalent of TL084ACD?

The TL084CD is a common pin-compatible equivalent for non-automotive applications, sharing the same 14-SOIC package and JFET quad op-amp architecture, but without the AEC-Q100 qualification. For automotive-grade needs, consider the TL084A-Q1 series if still available.

Can I use TL084CD instead of TL084ACD?

Yes, the TL084CD is pin-compatible and shares the same 14-SOIC package and electrical specifications, but it lacks the AEC-Q100 automotive qualification. For non-automotive designs, it is a direct substitute.
