A 281 KB PDF datasheet for the TL071, the low-noise JFET-input operational amplifier common in audio preamplifiers, mixers and measurement circuits. It lists pin functions, offset null connections, supply limits, noise and slew-rate figures, and sample circuits. Technicians use it to check DC conditions around the op amp, diagnose a stage that clips or hums, and confirm that a replacement part shares the same pinout and package. Compare the full marking on the board against the ordering information before substituting a similar op amp.
