LF412ACN/NOPB

Overview

The LF412ACN/NOPB is a dual JFET-input operational amplifier from the LF412-N series, manufactured by Texas Instruments. It features a metal can (MBCY8) or plastic DIP-8 package for through-hole mounting. Key electrical parameters include a gain-bandwidth product of 4 MHz and a slew rate of 15 V/µs. The input bias current is specified at 50 pA, with an input offset voltage of 1 mV. It operates on a supply voltage range of 10 V to 36 V (±5 V to ±18 V). The device supports a maximum output current of 25 mA and has a common-mode rejection ratio of 70 dB. Operating temperature ranges from 0°C to 70°C.

Feature Summary

• Dual JFET-input architecture providing high input impedance
• Internal frequency compensation eliminates external component requirements
• Low input bias current suitable for precision applications

Applications

• Precision analog signal processing circuits
• Active filter designs requiring low input current
• Integrator and differentiator circuits

Procurement Notes

Verify the specific package variant, as datasheets indicate both Metal Can (MBCY8) and Plastic DIP options for this part number family. Confirm RoHS compliance status via the manufacturer's official documentation, as suffixes may affect environmental certifications. Ensure the selected variant matches the required thermal and mechanical constraints for the target PCB layout.

Selection Notes

Select this component when high input impedance and low bias current are critical for signal integrity. The internal compensation simplifies design compared to uncompensated amplifiers. Consider the 4 MHz bandwidth limit for high-frequency applications. Verify that the 10 V minimum supply requirement aligns with the system power rails.

Part Context

This device belongs to the LF412-N series of dual operational amplifiers. It shares architectural similarities with other JFET-input op-amps but offers specific performance characteristics tailored for general-purpose analog applications. The NOPB suffix indicates lead-free and RoHS-compliant manufacturing standards.
