LF398P

Overview

The LF398P is a monolithic sample-and-hold circuit manufactured by Texas Instruments. It utilizes BI-FET technology to provide high-speed acquisition and low droop rates. The device operates within a supply voltage range of 5 V to 18 V and supports through-hole installation in an 8-pin PDIP package. It functions as a single-channel analog signal processor with a capture time of 4 μs, suitable for precision data acquisition systems operating between 0°C and +70°C.

Feature Summary

Monolithic integration of sample-and-hold functionality using BI-FET technology
Single-channel analog input processing capability
Through-hole mounting compatibility via standard packaging

Applications

Data acquisition systems requiring analog signal sampling
Frequency-to-voltage conversion circuits
Multiplexed analog input interfaces

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout and electrical characteristics. Ensure the component matches the required operational temperature range and supply voltage specifications for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a dedicated sample-and-hold amplifier is required for analog signal conditioning. Consider the BI-FET input stage for low bias current requirements. Evaluate the 8-pin PDIP package constraints against available board space. Confirm that the 4 μs capture time meets the system's bandwidth and sampling rate demands.

Part Context

The LF398 belongs to the LF398 family of monolithic sample-and-hold circuits produced by Texas Instruments. This series is designed for applications requiring precise analog signal storage and transfer. The device integrates the necessary switching and holding elements on a single chip, simplifying circuit design compared to discrete implementations.
