Overview
The LF198AH/NOPB is a monolithic sample and hold amplifier manufactured by Texas Instruments. It utilizes Bi-FET technology to provide high-speed signal acquisition capabilities. The device operates within an extended industrial temperature range from -55°C to +125°C. It is housed in a TO-99-8 metal can package designed for through-hole mounting. This component serves as a precision analog circuit for capturing and maintaining voltage levels.
Feature Summary
- Monolithic integration of sample and hold functions
- Bi-FET input technology for low bias current
- Extended industrial temperature operation capability
Applications
- Precision data acquisition systems
- Analog signal processing circuits
- High-speed sampling applications
Procurement Notes
Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status against the official datasheet. Confirm the TO-99-8 package dimensions match the mechanical outline drawing. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement.
Selection Notes
Select this component when a single-chip solution for analog signal sampling is required. The Bi-FET technology offers advantages in input impedance compared to bipolar counterparts. Consider the TO-99-8 package constraints for board layout and thermal management in high-temperature environments up to 125°C.
Part Context
This part belongs to the LF198 series of sample and hold amplifiers. It represents a specialized class of linear ICs distinct from operational amplifiers or voltage regulators. The family focuses on transient signal capture rather than continuous amplification, serving niche roles in instrumentation and control systems.
Replacement Considerations
Consult official substitution guides for compatible sample and hold amplifiers. Verify pinout compatibility and electrical parameter equivalence before replacing the original component with alternative manufacturers' parts.
