JFET op-amp in a through-hole DIP — what the ratings mean for your front end
The Texas Instruments TL071BCP is a single JFET-input operational amplifier in an 8-pin PDIP package, built for through-hole assembly. It delivers a 3 MHz gain-bandwidth product and a 13 V/µs slew rate, with a supply span from 10 V to 30 V single or dual rail. The JFET input stage holds input bias current to 65 pA, making it a natural fit for high-impedance signal conditioning — photodiode amplifiers, piezo sensor buffers, or precision integrators where a bipolar input stage would load the source. The commercial temperature grade (0°C to 70°C) limits it to indoor, bench, or controlled-environment equipment; it is not rated for automotive or industrial extended-range use.
JFET input — 65 pA bias current is the headline spec
Input bias current is 65 pA typical. Input offset voltage is 2 mV max.
Active lifecycle — no LTB risk for production BOMs
The TL071BCP carries an Active product status with ROHS3 compliance. There is no end-of-life notice, no last-time-buy window to track. For a BOM that needs a through-hole JFET op-amp, this part is a stable line-item that can be specified into new designs without worrying about a sudden discontinuation.
