LF298MX

Overview

The LF298MX is a monolithic sample-and-hold circuit manufactured by Texas Instruments. It operates within an industrial temperature range of -40°C to +85°C and utilizes an SOIC-8 surface-mount package. The device functions as a high-speed analog switch with hold capability, designed for precision data acquisition systems requiring accurate signal capture.

Feature Summary

• Monolithic integration of sampling switch and storage capacitor
• High-speed aperture time for precise signal timing
• Low droop rate during the hold phase

Applications

• Data acquisition systems
• Analog-to-digital converter front ends
• Signal processing circuits

Procurement Notes

Verify the specific suffix MX indicates the SOIC-8 tape and reel packaging variant. Confirm RoHS compliance status through the official datasheet, as historical versions may differ. Ensure the operating temperature range meets system requirements for industrial environments.

Selection Notes

Select this component when a compact, single-chip solution for sample-and-hold functionality is required. Compare aperture jitter and droop rates against alternative discrete implementations or other ICs in the LF198/LF298/LF398 family to ensure compatibility with the target application's speed and accuracy needs.

Part Context

The LF298MX belongs to the LFx98 family of monolithic sample-and-hold circuits from Texas Instruments. This series provides integrated switching and holding capabilities, simplifying the design of high-performance analog signal conditioning stages compared to discrete component solutions.
