Overview
The LF298MX/NOPB is a monolithic sample-and-hold circuit manufactured by Texas Instruments. It utilizes BI-FET technology and is housed in an SOIC-14 surface-mount package. The device operates on a single power supply ranging from 5 V to 18 V. Key electrical specifications include a capture time of 4 µs, an input bias current of 10 pA, and a droop rate of 3 mV/ms. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Monolithic integration of sample-and-hold functionality
- BI-FET input stage for low bias current
- Single-supply operation capability
Applications
- Data acquisition systems
- Analog signal processing circuits
- Communication equipment
Procurement Notes
Verify the specific suffix 'MX' confirms the SOIC-14 surface-mount package and 'NOPB' indicates lead-free/RoHS compliance. Confirm the manufacturer is Texas Instruments. Ensure the component matches the LFx98 family specifications for capture time and droop rate. Check for any specific environmental or handling requirements listed in the official datasheet.
Selection Notes
Select this component when a surface-mount sample-and-hold amplifier with low input bias current is required. The LF298MX/NOPB offers a capture time of 4 µs and operates on a single supply voltage up to 18 V. Consider the SOIC-14 package size and the operating temperature range of -40°C to +85°C for system compatibility.
Part Context
The LF298 is part of the LFx98 family of monolithic sample-and-hold circuits from Texas Instruments. This family includes variants such as the LF198, LF298, and LF398, which share similar core architectures but may differ in performance grades or packaging options. The LF298MX/NOPB specifically denotes the industrial grade version in a surface-mount package.
