LF412CN/NOPB

Overview

The LF412CN/NOPB is a dual JFET-input operational amplifier from the LF412-N series, manufactured by Texas Instruments. It features a gain-bandwidth product of 4 MHz and a slew rate of 15 V/µs. The device operates within a supply voltage range of -18 V to +18 V. Key electrical parameters include an input bias current of 2 nA and an input offset voltage of 3 mV. It is housed in an 8-pin MDIP package designed for through-hole mounting.

Feature Summary

• Dual-channel architecture with JFET inputs providing low input bias current
• High-speed performance characterized by a 4 MHz gain-bandwidth product
• Wide single or dual power supply operation capability

Applications

• Precision analog signal processing circuits
• Audio preamplifier stages requiring low noise
• Active filter implementations

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the package type matches the required MDIP form factor for your PCB layout. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement.

Selection Notes

Select this component when a dual op-amp with JFET inputs is required for high impedance applications. Compare the 4 MHz bandwidth against system requirements to ensure adequate speed. Verify that the 15 V/µs slew rate meets dynamic signal handling needs without distortion.

Part Context

This part belongs to the LF412-N family of dual operational amplifiers. It serves as a lead-free, RoHS-compliant version of the standard LF412CN. The device utilizes BiFET technology to combine the low noise of JFET inputs with the ease of use of bipolar outputs.

Replacement Considerations

The LF412CN is listed as obsolete on some distributor platforms; the LF412CN/NOPB is the active replacement variant. Cross-reference with other LF412 variants like LF412CH for military-grade temperature ranges if necessary.
