The TL071IDR is a single J-FET input operational amplifier from Texas Instruments, in an 8-SOIC package. The J-FET front end gives it a 65 pA typical input bias current and a 3 MHz gain-bandwidth product, with a 13 V/µs slew rate. It runs on a 10 V to 30 V total supply span — comfortable on ±5 V to ±15 V split rails or a single 12 V or 24 V rail. The single-channel format means one op-amp per package, so a quad-channel design needs four of these.
Supply range and temperature — where it lives
Good for outdoor telecom, factory-floor sensor conditioning, and motor-drive feedback paths that sit away from the hot junction. Supply current is 1.4 mA typical — not a micropower part, but reasonable for a general-purpose J-FET amp on a 24 V industrial rail.
