LF298M

Overview

The LF298M is a monolithic sample-and-hold circuit manufactured by Texas Instruments. It features a 10-microsecond acquisition time and a 3-millivolt offset voltage. The device operates within a temperature range of -40°C to +125°C and is available in a 14-pin SOIC package. It accepts analog input signals and functions as a dedicated sample and hold amplifier.

Feature Summary

• Monolithic integration for compact circuit design
• Fast acquisition capability for signal sampling
• Low offset voltage for improved accuracy

Applications

• Analog signal processing systems
• Data acquisition circuits
• Precision measurement instrumentation

Procurement Notes

Verify the specific suffix (e.g., M, MX) against the required package type and operating temperature grade. Confirm RoHS compliance status via the official datasheet, as availability may vary by region. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application design.

Selection Notes

Select this component when a high-speed sample-and-hold function with low offset is required in a surface-mount format. Consider the 14-pin SOIC package constraints and the specified operating temperature range. Evaluate if the 10-microsecond acquisition time meets the system's timing requirements compared to alternative devices.

Part Context

This component belongs to the LF298 series of monolithic sample-and-hold circuits from Texas Instruments. It is designed for applications requiring precise analog signal capture. The device serves as a fundamental building block for converting continuous analog signals into discrete values for further processing or digitization.

Replacement Considerations

Check for direct substitutes such as the LF298MX/NOPB variant which shares similar characteristics but may differ in packaging or reel configuration. Verify functional compatibility before substitution.
