LF412CD

Overview

The LF412CD is a dual JFET-input operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 3 MHz and a slew rate of 13 V/us. The device operates on power supplies ranging from ±3.5V to ±18V (7V to 36V single supply). Each channel consumes 4.5 mA of current. The input offset voltage maximum is 3 mV. It is housed in an 8-pin SOIC package and functions within a temperature range of 0°C to 70°C.

Feature Summary

• JFET input stage provides high input impedance
• Dual-channel configuration for compact designs
• High slew rate supports fast signal transitions

Applications

• Audio preamplifier circuits
• Active filter implementations
• General-purpose analog signal conditioning

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical tolerances. Ensure the ordering part number matches the required package style and temperature grade. Cross-reference datasheet revisions to validate parameter consistency before integration into production hardware.

Selection Notes

Select this component when high input impedance and moderate speed are required for dual-channel applications. Compare performance metrics such as slew rate and bandwidth against alternative JFET op-amps if higher precision or wider operating temperatures are necessary for the specific design constraints.

Part Context

This device belongs to the LF412 family of dual JFET operational amplifiers. It shares architectural similarities with other members like the LF412CH/NOPB but differs in packaging and environmental specifications. The CD variant specifically denotes the plastic SOIC package suitable for surface-mount assembly.

Replacement Considerations

Cross-reference with LF412CDR or LF412CDRG4 for identical functionality in tape-and-reel formats. Verify pin compatibility with other dual JFET op-amps only after confirming electrical parameter alignment.
