LF356BMX

Overview

The LF356BMX is a single JFET-input operational amplifier manufactured by National Semiconductor. It features a gain bandwidth product of 5 MHz and a slew rate of 12 V/us. The device operates on power supplies ranging from 10V to 36V or ±5V to ±18V. Each channel consumes 5mA of current. The maximum input offset voltage is specified at 13,000 uV. It is housed in an 8-pin SOP package.

Feature Summary

• JFET input stage for high input impedance
• Wide bandwidth performance
• Low supply current consumption
• High slew rate capability

Applications

• Audio preamplifiers
• Active filters
• Voltage followers

Procurement Notes

Verify the manufacturer origin as National Semiconductor or Texas Instruments due to acquisition history. Confirm the suffix BMX indicates the specific tape-and-reel packaging variant. Ensure the component matches the original National Semiconductor specifications rather than generic equivalents.

Selection Notes

Select this component when high input impedance and moderate speed are required. It serves as a suitable alternative to TL081 series devices. Consider the 13mV max offset voltage for precision requirements. Verify compatibility with the intended supply voltage range before integration.

Part Context

This part belongs to the LF35x family of JFET input operational amplifiers. It shares architectural similarities with the LF156 and LF256 series. The device was originally designed by National Semiconductor before the company's acquisition by Texas Instruments. It represents a standard solution for general-purpose analog signal processing applications.

Replacement Considerations

• TL081CN
• LF156CN
