The Texas Instruments LF356N/NOPB is a single JFET-input op-amp from the BI-FET™ series, packaged in an 8-DIP through-hole body (0.300" wide, 7.62 mm pitch). It delivers a 5 MHz gain-bandwidth product and a 12V/µs slew rate, with 30 pA typical input bias current and 3 mV input offset voltage. Supply current runs 5 mA quiescent, and the part operates from a single or split supply up to 30 V total.
What the ratings mean on the bench
The 12V/µs slew rate and 5 MHz GBW set the usable bandwidth. The 30 pA input bias current suits high-impedance sources.
