The LF347DT is a quad operational amplifier in a 14pin SO14 package. This listing includes 13 pieces. Key benefits Four independent opamps in a single package enable compact, costefficient designs. JFETinput architecture offers input impedance and low input bias current, which helps improve accuracy with impedance sources. Flexible, suitable for a wide range of standard opamp configurations (inverting, noninverting, summing, differential). Reliable performance in compact, surfacemount layouts thanks to the SO14 packaging. Key attributes Function: Quad operational amplifiers Input type: JFET Package: SO14 (14pin smalloutline) Mounting: surfacemount Compatibility: suitable for standard opamp circuit configurations and applications Performance: gain and broad applicability for general analog amplification and conditioning Applications and use cases Sensor signal conditioning: ideal for impedance sensors such as photodiodes, thermocouples, and bridge sensors, where low bias current and input impedance improve accuracy. Active filters and signal processing: suitable for building lowpass, pass, bandpass, and complex filter networks in audio or instrumentation systems. General purpose amplification and instrumentation: useful in prototypes, test rigs, educational projects, and compact analog signal paths requiring multiple opamps in one package.
