JFET input stage — 65 pA bias current
The TL074ING4 is a quad JFET-input operational amplifier from Texas Instruments, part of the TL074 series. Its 65 pA typical input bias current and 3 mV input offset voltage make it a natural fit for high-impedance signal conditioning — photodiode amplifiers, piezo sensor buffers, and precision integrators where bipolar input stages would load the source.
Slew rate and bandwidth — 13V/µs at 3 MHz
With a 13V/µs slew rate and 3 MHz gain-bandwidth product, this op-amp handles audio-band signals and moderate-speed control loops without slew-induced distortion.
