LF412CPG4

Overview

The LF412CPG4 is a dual operational amplifier manufactured by Texas Instruments. It features JFET input transistors to achieve high input impedance and low bias current. The device provides a bandwidth of 4 MHz and a slew rate of 7 V/µs. It operates within a supply voltage range of ±5V to ±18V. The component is housed in an 8-pin plastic small outline package (SOIC) compliant with the G4 lead-free suffix.

Feature Summary

• Dual operational amplifier architecture with JFET inputs for high impedance
• Low input offset voltage and drift characteristics
• Wide single or split power supply operation capability

Applications

• Precision signal conditioning circuits
• Active filter designs
• Transimpedance amplification

Procurement Notes

Verify the presence of the G4 suffix to confirm lead-free compliance and RoHS status. Ensure the package designation matches the required SOIC-8 footprint. Confirm that the manufacturer source is Texas Instruments to avoid counterfeit components. Cross-reference the full part number against official distributor catalogs for accurate identification.

Selection Notes

Select this component when high input impedance and low bias current are required for precision analog applications. Consider the 4 MHz bandwidth and 7 V/µs slew rate for moderate-speed signal processing tasks. Evaluate the operating temperature range and supply voltage requirements against system constraints before implementation.

Part Context

This device belongs to the LF412 family of dual JFET-input operational amplifiers. It serves as a general-purpose analog building block designed for applications requiring high input impedance without the need for external compensation. The G4 suffix indicates a specific manufacturing revision focused on environmental compliance.
