125°C operating range and JFET input stage
The 3 mV input offset voltage (max) is adequate for general-purpose signal chains; for sub-mV precision, a chopper-stabilized amplifier would be needed.
Supply and package fit
Operating from a single 10 V to 30 V supply or split ±5 V to ±15 V rails, the TL084QDG4 fits existing ±15 V industrial rails without a regulator. The 14-SOIC (0.154-inch body width) footprint is shared across the TL084 family, so a board laid out for the commercial TL084CN can accept this automotive-grade variant with no layout change.
