LF398AN/NOPB

Overview

The LF398AN/NOPB is a monolithic sample and hold circuit manufactured by Texas Instruments. It utilizes BI-FET technology to provide high-speed acquisition capabilities, with a capture time of 4 microseconds. The device operates on a single power supply ranging from 5 V to 18 V and supports an analog input type. Designed for through-hole installation, it is housed in an 8-pin PDIP 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 functionality
BI-FET technology implementation
Single power supply operation capability

Applications

Data acquisition systems utilizing ADC0816 and ADC0817
Frequency-to-voltage converters requiring improved response and ripple reduction
Applications using ADC0808/809 8-bit microprocessor-compatible ADCs

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics match the required design specifications. Ensure the ordering part number corresponds exactly to the desired package style and operating temperature range. Cross-reference the manufacturer's latest datasheet to confirm compliance with current environmental directives and material declarations before finalizing procurement.

Selection Notes

Select this component when a dedicated external sample and hold amplifier is required to interface with analog-to-digital converters. It is suitable for applications needing to prevent amplitude deviation during conversion intervals. Consider the 4-microsecond capture time and single-supply voltage requirements when designing the signal conditioning stage prior to the ADC input.

Part Context

This component belongs to the LF398 series of sample and hold amplifiers. It serves as a discrete solution for capturing and holding analog signals, distinct from integrated solutions found within modern ADCs. The device addresses the need for precise signal sampling in systems where the input signal changes rapidly relative to the conversion time.
