LF412CDRE4

Overview

The LF412CDRE4 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/µs. The device operates on supply voltages ranging from ±3.5 V to ±18 V (7 V to 36 V 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 providing low bias current
• High slew rate for fast signal response
• Wide single or dual power supply operation

Applications

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

Procurement Notes

Verify the E4 suffix indicates lead-free composition and RoHS compliance per Texas Instruments standards. Confirm the SOIC-8 package dimensions match the design footprint. Ensure the commercial temperature range (0°C to +70°C) meets system requirements. Cross-reference the datasheet revision date to ensure parameter accuracy.

Selection Notes

Select this component when JFET input impedance is required with moderate speed. Compare against the LF411 for single-channel needs or the TL092 for alternative pinouts. Verify that the 3 MHz bandwidth suffices for the target frequency response. Check if the 13 V/µs slew rate prevents distortion in high-speed applications.

Part Context

This part belongs to the LF412 family of dual JFET-input operational amplifiers. The E4 suffix denotes environmental compliance, specifically lead-free packaging. It shares architectural similarities with the LF353 and TL082 series but offers specific performance characteristics defined by its JFET inputs and bipolar output stages.

Replacement Considerations

• LF412CDR
• LF412CDRG4
