LF356M

Overview

The LF356M is a single JFET-input operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 5 MHz and a high slew rate of 12 V/us. The device operates on dual supply voltages ranging from ±5 V to ±18 V, or a single supply from 10 V to 36 V. Key electrical parameters include an input bias current of 200 pA, an input offset voltage of 10 mV, and a common-mode rejection ratio of 100 dB. It is housed in an 8-SOIC surface-mount package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates matched high-voltage JFETs with standard bipolar transistors using BI-FET technology for low noise performance.
• Features internal compensation and large differential input voltage capability for stable operation.
• Includes offset adjustment functionality that does not degrade drift or common-mode rejection ratios.

Applications

• Signal processing circuits
• Audio equipment
• Communication and network systems

Procurement Notes

Verify component authenticity through authorized distributors as the LF356M may be discontinued. Confirm RoHS compliance status, as some sources indicate non-compliance. Ensure the SOIC-8 package matches design requirements. Check for equivalent NOPB variants if lead-free specifications are mandatory for the target assembly process.

Selection Notes

Select this component for applications requiring low input bias current and high slew rate. The JFET input stage suits high-impedance signal sources better than bipolar alternatives. Consider the 8-SOIC package for surface-mount designs. Evaluate the 5 MHz bandwidth against system frequency requirements before finalizing the selection.

Part Context

The LF356M belongs to the LF356 series of JFET input operational amplifiers. This family includes variants such as the LF356N (PDIP) and LF356H/NOPB (TO-99). The M suffix specifically denotes the 8-SOIC surface-mount package variant designed for commercial temperature ranges.
