The TL081ACP is a JFET-input operational amplifier from Texas Instruments in an 8-pin DIP through-hole package. The JFET input stage gives it a 30 pA input bias current and 3 mV input offset voltage, making it a solid choice for general-purpose signal conditioning, active filters, and audio preamplifiers where high input impedance matters. The supply range spans 7 V to 36 V, so it works from single or split rails.
The 3 MHz GBW and 13 V/µs slew rate support audio and low-speed sensor interfaces. The 30 pA input bias current allows 1 MΩ feedback resistors without significant DC offset error.
