LF412CN

Overview

The LF412CN 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 on dual power supplies ranging from -18 V to +18 V. Key electrical parameters include an input bias current of 2 nA, an input offset voltage of 3 mV, and an input noise current density of 10 fA. It is housed in an 8-pin MDIP package suitable for through-hole mounting.

Feature Summary

• Dual JFET input stage providing low input bias current
• High slew rate for fast signal response
• Low input offset voltage and drift characteristics

Applications

• Precision analog signal processing circuits
• Audio preamplifier stages
• Data acquisition systems requiring low leakage

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical tolerances. Ensure the component matches the required operating temperature range and package dimensions for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when low input bias current and high slew rate are critical requirements. Compare the 4 MHz bandwidth against application needs. Verify that the 8-pin DIP package fits the assembly constraints. Consider the input offset voltage specifications relative to the required signal accuracy in the design.

Part Context

This device belongs to the LF412-N family of dual operational amplifiers. It utilizes JFET input technology to achieve superior performance compared to standard bipolar inputs. The LF412CN variant specifically denotes the commercial temperature grade version packaged in a standard dual in-line format.

Replacement Considerations

The LF412CN/NOPB is a verified lead-free replacement for the LF412CN. Verify pin compatibility and electrical specifications before substitution.
