LF356MX

Overview

The LF356MX is a single JFET-input operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It features a gain-bandwidth product of 5 MHz and a high slew rate of 12 V/µs. The device operates on a supply voltage range of 10 V to 36 V (or ±5 V to ±18 V). Key electrical parameters include a maximum input offset voltage of 10 mV, input bias current of 200 pA, and common-mode rejection ratio of 80 dB. It functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• JFET input stage providing low input bias current
• High slew rate for fast signal response
• Wide single or dual power supply operation

Applications

• Audio preamplifiers
• Active filters
• Voltage followers

Procurement Notes

Verify the specific suffix 'MX' against the official Texas Instruments datasheet to confirm it denotes the SOIC-8 tape-and-reel packaging variant. Ensure the component matches the required operating temperature range and pinout configuration for your circuit design before procurement.

Selection Notes

Select this component when a JFET-input op amp with moderate bandwidth and high slew rate is required in a compact surface-mount form factor. Compare input bias current and noise specifications against other LF356 variants if lower power consumption or different packaging options are needed.

Part Context

This part belongs to the LF356 family of JFET-input operational amplifiers from Texas Instruments. The 'M' indicates the SOIC package, while 'X' typically specifies reel packaging. It serves as a general-purpose amplifier suitable for applications requiring low input current and wide supply voltage flexibility.

Replacement Considerations

Check for direct equivalents such as LF356M/NOPB or LF356N depending on package requirements. Verify that any substitute maintains compatible JFET input characteristics and pinout compatibility.
