LF353N/NOPB

Overview

The LF353N/NOPB is a dual wide-bandwidth high-speed JFET input operational amplifier manufactured by Texas Instruments. It utilizes BI-FET II technology for internally trimmed input offset voltage, ensuring low power consumption while maintaining high gain-bandwidth product and fast slew rate. The device features matched high-voltage JFET input devices that provide very low input bias and offset currents. It operates within a supply voltage range of 10V to 36V and is housed in an 8-pin PDIP package.

Feature Summary

• BI-FET II technology enables internal trimming of input offset voltage for improved precision.
• High-voltage JFET inputs deliver extremely low input bias current and high input impedance.
• Wide bandwidth and high slew rate support high-speed signal processing applications.
• Low power supply current requirement maintains efficiency without sacrificing performance.

Applications

• High-speed integrator circuits
• Fast digital-to-analog converters (D/A)
• Sample-and-hold circuits

Procurement Notes

Verify the specific manufacturer source, as the LF353 series was originally from National Semiconductor before acquisition by Texas Instruments. Confirm the datasheet version matches the NOPB suffix requirements for lead-free compliance. Ensure the DIP-8 package dimensions align with your PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when upgrading existing LM1558 or LM358 designs to achieve better overall performance. It is suitable for applications requiring low input offset voltage, low input bias current, and high conversion rates. Consider the 8-pin PDIP package for through-hole mounting needs where surface mount options are not feasible.

Part Context

This part belongs to the LF353 family of dual JFET input operational amplifiers. It is pin-compatible with standard LM1558 designs, facilitating direct upgrades. The NOPB suffix indicates a lead-free, halogen-free green product compliant with RoHS standards, distinguishing it from older non-compliant variants in the same series.
