LF412CDG4

Overview

The LF412CDG4 is a dual JFET-input operational amplifier manufactured by Texas Instruments. It features very low input offset voltage and drift, ensuring high precision in signal processing applications. The device operates within a supply voltage range of ±3.5V to ±18V (7V to 36V single supply). Key electrical characteristics include a bandwidth of 3MHz and a slew rate of 13V/µs. It is housed in an 8-pin SOIC package.

Feature Summary

• Dual JFET-input architecture for low noise performance
• Very low input offset voltage and drift
• High slew rate and wide bandwidth

Applications

• Precision analog signal conditioning
• Active filters
• Transducer amplifiers

Procurement Notes

Verify the component status as the LF412CDG4 may be listed as obsolete or not in production by the manufacturer. Confirm availability through authorized distributors and check for recommended replacement parts if current stock is unavailable. Ensure the datasheet revision matches the required specifications for your design.

Selection Notes

Select this component for applications requiring low input bias current and high input impedance due to its JFET inputs. It is suitable where low offset voltage is critical. Compare against the LF412CDR variant for packaging differences. Ensure the operating temperature range meets system requirements.

Part Context

This part belongs to the LF412 family of dual operational amplifiers. It is a pin-compatible and functionally similar alternative to the LF412CDR, differing primarily in the tape-and-reel packaging format indicated by the 'DG4' suffix. Both are JFET-input devices designed for general-purpose analog applications.

Replacement Considerations

The LF412CDR is a direct functional substitute with identical electrical specifications but in a different package configuration.
