LF398S8#TRPBF

Overview

The LF398S8#TRPBF is a precision sample and hold amplifier manufactured by Analog Devices Inc. It features a single channel with a capture time of 20 µs. The device operates within a temperature range of 0°C to +70°C and utilizes BI-FET technology. It is housed in an 8-pin TO-99 metal can package designed for through-hole mounting.

Feature Summary

• Precision analog signal sampling and holding capability
• BI-FET input technology for low leakage performance

Applications

• Data acquisition systems requiring precise voltage snapshotting
• Analog-to-digital converter front-end conditioning
• Signal processing circuits needing temporary storage of analog waveforms

Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation, as this indicates tape-and-reel packaging which may differ from standard bulk or tube distributions. Confirm that the manufacturer designation matches current corporate records following industry consolidations. Ensure the component meets all required environmental and regulatory standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a high-precision sample and hold function is required with a capture time specification of 20 µs. The BI-FET architecture offers distinct advantages over older bipolar technologies regarding input bias currents. Consider the TO-99 package constraints for board layout and thermal management requirements compared to surface-mount alternatives.

Part Context

This part belongs to the LF398 family of precision sample and hold amplifiers. The series is characterized by its ability to accurately track and hold analog signals for subsequent processing stages. The specific model integrates the core amplifier functionality into a robust metal can package suitable for industrial and commercial applications.
