LF412CP

Overview

The LF412CP is a dual high-speed operational amplifier manufactured by Texas Instruments. It features a JFET input stage and bipolar output, utilizing BiFET II technology for low power consumption and high speed. Key electrical parameters include a gain-bandwidth product of 3 MHz, a slew rate of 13 V/us, and an input bias current of 200 pA. The device operates on supply voltages ranging from 10 V to 40 V (dual supplies ±3.5 V to ±18 V) with a maximum operating temperature of +70 C. It provides a common-mode rejection ratio of 100 dB and delivers 25 mA output current per channel in a PDIP-8 package.

Procurement Notes

Verify the specific suffix 'CP' corresponds to the commercial temperature range and PDIP-8 package configuration as listed in the official datasheet. Confirm RoHS compliance status through the manufacturer's documentation before procurement. Ensure the ordering part number matches the exact pinout and electrical specifications required for the design.

Selection Notes

Select this component when a dual-channel amplifier with JFET inputs is required for applications needing moderate bandwidth and low noise. Compare against other members of the LF412 family if industrial temperature ranges or different packaging options are necessary. Verify that the 3 MHz gain-bandwidth product meets the system's frequency response requirements.

Part Context

This device belongs to the LF412 series of dual operational amplifiers produced by Texas Instruments. The series utilizes BiFET II technology to combine the advantages of JFET inputs with bipolar outputs. The LF412CP represents the commercial grade variant housed in a standard plastic dual in-line package, designed for general-purpose analog signal conditioning tasks.

Replacement Considerations

Check the official datasheet for confirmed substitute part numbers within the same family or equivalent devices from other manufacturers. Ensure any replacement maintains compatible pinouts, supply voltage ranges, and electrical performance characteristics.
