Datasheet in PDF (236 KB) for the TL081, a single JFET-input operational amplifier widely found in audio gear, filters, power supply control loops and instrumentation. It provides the pinout, supply range, offset adjustment pins, input characteristics and typical application circuits. When repairing analogue stages, use it to verify pin voltages, confirm the package variant printed on the part, and pick a compatible substitute. Check the full marking suffix, since package type and temperature grade can differ between versions of the same device.
