LF398M/NOPB

Overview

The LF398M/NOPB is a monolithic sample and hold amplifier manufactured by Texas Instruments. It utilizes BI-FET technology to provide high-speed acquisition capabilities, with a capture time specified at 4 microseconds in official documentation. The device operates on a single analog input channel and supports a supply voltage range from 5 V to 18 V. Designed for through-hole surface mount applications, it is housed in an SOIC-14 package. The component functions within a temperature range of 0°C to +70°C and complies with RoHS standards.

Feature Summary

Monolithic integration of sample and hold circuitry using BI-FET technology
Single-channel analog signal processing capability
Supports wide dual-polarity or single-supply operation within specified voltage limits

Applications

Data acquisition systems requiring precise signal freezing
Frequency-to-voltage conversion circuits
Analog-to-digital converter front-end conditioning

Procurement Notes

Verify the specific suffix 'M' indicates the SOIC-14 surface-mount package variant distinct from the PDIP version. Confirm RoHS compliance status via the manufacturer's current datasheet. Ensure the operating environment remains within the documented commercial temperature range. Validate pinout compatibility during PCB layout to prevent interface errors.

Selection Notes

Select this component when a single-channel sample and hold function is required with moderate speed requirements. The BI-FET input stage offers low leakage characteristics suitable for precision applications. Consider the SOIC-14 package constraints for board space. Verify that the 4 microsecond capture time meets the system's bandwidth needs.

Part Context

This part belongs to the LF398 family of sample and hold amplifiers. It serves as a bridge between analog sensors and digital converters. The NOPB suffix denotes lead-free and RoHS compliant manufacturing. It is distinct from comparator or regulator ICs in the same catalog.
