JFET quad op-amp in a 14-pin DIP – what you get
The TL074ACNG4 is a JFET-input quad operational amplifier from Texas Instruments in a 14-pin plastic DIP (14-PDIP, 0.300-inch body).
Supply range and quiescent draw
Runs from a single supply as low as 10 V up to 30 V, or split rails (±5 V to ±15 V). The whole quad draws 1.4 mA typical per amplifier – 5.6 mA total at no load – which keeps the thermal rise low in the 14-PDIP package even when all four stages are active.
Commercial temperature grade – design-in boundary
That is commercial grade, not industrial. If your BOM needs -40°C operation or the board lives in an outdoor cabinet, you step up to the TL074I or TL074M variants. For benchtop instrumentation, studio gear, or indoor control panels the AC grade fits fine.
It is a current, standard-product line – the same JFET quad architecture that has been in production for decades, still available through distribution. Sourced per RFQ; tube quantity is the standard delivery format.
