The TL074QDREPA is a quad JFET-input operational amplifier from Texas Instruments in a 14-SOIC surface-mount package. Each of the four channels draws 1.4 mA supply current, keeping the total quiescent draw under 6 mA for the package — relevant for multi-channel designs on a shared rail.
Last-time-buy — secure stock or qualify a replacement now
This is the final ordering window; once the manufacturer's last-time-buy date passes, the part will no longer be produced. Buyers should secure their lifetime-buy quantity or begin qualifying a pin-compatible alternative from the TL074 family.
Industrial temperature range and JFET input stage
The JFET input stage provides an input bias current of 65 pA typical, which is orders of magnitude lower than a bipolar-input op-amp. This matters in high-impedance sensor interfaces and precision integrators where bias current error would otherwise dominate the offset budget. Output type is push-pull, capable of sourcing or sinking 10 mA per channel — adequate for driving the input of an ADC or a following stage, but not intended for heavy loads like a speaker or relay coil.
