Overview
The LF298H/NOPB is a monolithic sample-and-hold circuit manufactured by Texas Instruments. It utilizes BI-FET technology and is housed in an 8-pin TO-99 metal can package (TO-99-8). The device operates within a temperature range of 0°C to +70°C and supports through-hole mounting. It functions as a single-channel analog signal processor designed for precision data acquisition applications requiring accurate voltage capture and retention.
Feature Summary
- Monolithic integration of sample-and-hold functionality using BI-FET technology
- High-performance analog signal processing for data acquisition systems
- Robust metal can packaging suitable for industrial environments
Applications
- Precision data acquisition systems
- Analog signal conditioning circuits
- Industrial control instrumentation
Procurement Notes
Verify the specific datasheet revision and electrical characteristics against the official Texas Instruments documentation before integration. Confirm that the TO-99-8 package dimensions and pinout match the target PCB layout requirements. Ensure the operating temperature range aligns with the environmental conditions of the final application to guarantee reliable performance.
Selection Notes
Select this component when a high-reliability, hermetically sealed sample-and-hold amplifier is required for analog signal processing. The BI-FET input stage offers distinct advantages for specific impedance matching needs compared to bipolar alternatives. Evaluate the thermal management requirements associated with the metal can package during the design phase.
Part Context
This part belongs to the LFx98 family of monolithic sample-and-hold circuits from Texas Instruments. It shares functional similarities with the LF198 and LF398 series but may differ in specific electrical parameters or manufacturing specifications. The 'H' suffix typically denotes a military-grade or enhanced reliability variant within the broader product line.
Replacement Considerations
The LF198H/NOPB and LF398H/NOPB are related members of the same family. Verify pin compatibility and specific electrical tolerances before substituting these parts. Cross-reference the official datasheets to ensure functional equivalence in the intended application.
