Overview
The LF398H is a monolithic sample and hold amplifier manufactured by Texas Instruments. It utilizes BI-FET technology to provide high-speed analog signal processing capabilities. The device features a capture time of 20 microseconds, ensuring rapid acquisition of input signals. It operates within a temperature range from 0°C to +70°C. The component is housed in an 8-pin TO-99 metal can package designed for through-hole mounting.
Feature Summary
- Monolithic integration of sample and hold circuitry using BI-FET technology
- High-speed analog signal acquisition with specified capture time
- Robust metal can packaging suitable for demanding environments
Applications
- Data acquisition systems requiring precise signal sampling
- Analog-to-digital converter front-end conditioning
- Frequency-to-voltage conversion circuits
Procurement Notes
Verify the specific suffix H against official Texas Instruments documentation to confirm the exact package type and performance grade. Ensure the procurement channel provides valid RoHS compliance details as indicated in manufacturer specifications. Confirm that the through-hole TO-99-8 package matches your board layout requirements before finalizing orders.
Selection Notes
Select this component when a dedicated sample and hold function is required rather than an integrated ADC solution. Consider the 20-microsecond capture time relative to your system's bandwidth needs. Evaluate the TO-99 package constraints against available PCB space and mounting methods compared to plastic alternatives like the LF398N.
Part Context
This part belongs to the LF398 series of sample and hold amplifiers produced by Texas Instruments. It serves as a specialized analog interface component bridging continuous analog signals and discrete digital processing stages. The family is known for its reliability in industrial instrumentation applications.
Replacement Considerations
The LF398N/NOPB offers similar functionality but differs in package style (PDIP) and capture time specifications. Verify electrical compatibility and physical footprint differences before substituting.
