This listing includes five pieces of the LF347N in a DIP14 package. The LF347N is a quad, JFETinput operational amplifier in a standard DIP14 form factor, designed for versatile analog signal processing. Key benefits Four opamps in a single package: reduces board space and component count while enabling compact circuit designs. JFETinput architecture: provides input impedance and low input bias currents, helping preserve small signal integrity from sensors and transducers. Flexible linear amplification: suitable for a wide range of standard opamp configurations, including inverting, noninverting, voltage follower, summing, and filter circuits. Easy handling and compatibility: DIP14 package supports straightforward handsoldering, prototyping, and interchangeability in compatible circuits. Key attributes Function: quad operational amplifier Package: DIP14 Configuration: four independent opamps within a single package Model: LF347N Quantity: 5 pieces included in this listing Target applications: general analog signal amplification and conditioning in laboratory, electronics prototyping, and small to medium scale production Applications and use cases Audio and activefilter front ends: build preamps, tone control, and filter stages with minimal component count. Sensor signal conditioning: amplify and buffer signals from sensors with source impedance before ADC or further processing. Data acquisition and instrumentation: create signal conditioning blocks, summing networks, and isolation buffers for measurement systems. Compatibility and usage notes Designed for standard opamp circuit configurations in diverse analog applications. DIP14 packaging is compatible with typical breadboards and socketbased prototyping, as well as compact PCB designs. Suitable for use in systems requiring multiple, identical opamp channels in a single package.
