Description

The LF412 from Texas Instruments is a precision dual JFET-input operational amplifier designed for low offset voltage, low drift, and high input impedance applications. Its JFET input stage provides extremely low input bias current, making it ideal for high-impedance signal sources and sensitive analog circuits. With a gain bandwidth of 3MHz and a fast slew rate of 15V/µs, the LF412 delivers improved performance over standard bipolar op-amps in precision amplification, active filtering, instrumentation, and audio signal processing applications. Features • Dual JFET input operational amplifier • High input impedance for sensitive analog signals • Very low input bias current (picoampere range) • Low input offset voltage • Low offset voltage drift for temperature stability • High slew rate of approximately 15V/µs • Gain bandwidth product of 3MHz • Low noise operation • Wide supply voltage range • Suitable for precision analog circuits • Better performance than standard 741 op-amps • Available in DIP-8 and SOIC-8 packages • Ideal for instrumentation and audio applications • Unity-gain stable operation
