Dual JFET op-amp in 8-DIP — 4 MHz GBW, 15 V/µs slew
The LF412ACN/NOPB is a dual JFET-input operational amplifier from Texas Instruments, housed in an 8-pin DIP (0.300", 7.62 mm) through-hole package. It delivers a gain-bandwidth product of 4 MHz and a slew rate of 15 V/µs — fast enough for audio-band signal conditioning, active filters, and precision integrators without sacrificing DC accuracy.
Supply range and temperature grade
Operates from a single or split supply spanning 10 V to 44 V total, with a quiescent current of 3.6 mA per channel. The 0°C to 70°C temperature grade suits bench instruments, lab equipment, and commercial-grade control boards.
DC precision and input characteristics
Input offset voltage is 500 µV max, input bias current is 50 pA — the JFET front end keeps drift low in high-impedance sensor interfaces and sample-and-hold stages. Two circuits in one package saves board space for dual-channel signal chains.
