Overview
The LF347M/NOPB is a quad JFET input operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 4 MHz and a slew rate of 13 V/us. The device operates within a supply voltage range of 8 V to 36 V, with a maximum dual supply of 18 V. Input offset voltage is specified at 10 mV, while input bias current is 200 pA. Common-mode rejection ratio ranges from 70 dB to 100 dB. The component is housed in an SOIC-14 surface-mount package and supports an operating temperature range from 0°C to +70°C.
Feature Summary
- Quad JFET input architecture providing high-speed performance
- Wide bandwidth capability for signal processing applications
- Low input bias current characteristics
Applications
- High-speed analog signal conditioning circuits
- Precision instrumentation amplifiers
- Audio processing stages requiring low noise
Procurement Notes
Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical tolerances. Ensure the SOIC-14 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a quad configuration with JFET inputs is required for high-speed applications. Compare the 4 MHz gain-bandwidth product against system requirements. Evaluate the 13 V/us slew rate for dynamic signal handling. Consider the SOIC-14 package for surface-mount assembly constraints.
Part Context
This part belongs to the LF347 family of wide bandwidth quad operational amplifiers. It serves as a surface-mount variant of the through-hole LF347N. The NOPB suffix indicates lead-free construction compliant with environmental standards. It is designed for general-purpose high-speed analog applications.
Replacement Considerations
Cross-reference with LF347MX/NOPB for identical electrical specifications in alternative packaging. Verify functional compatibility with LF347M-NOPB variants. Consult official substitution guides for package-specific mechanical differences.
