The Fairchild 215 C is a type of dual-\N-channel junction field-effect transistor (JFET). It is a versatile and high precision JFET that is commonly used in precision circuits where low input noise and high input impedance are required. The dual-\N-channel design of the Fairchild 215 C means that it has two separate JFETs, each with its own gate, source, and drain terminals. This allows for flexible circuit design where two separate LOW noise, high input impedance inputs can be used simultaneously.Some notable features of the Fairchild 215 C include:- Low input noise: The Fairchild 215 C has a very low input noise voltage of less than 10 nV/\sqrt{Hz}. This makes it particularly well-suited for precise amplitude comparisons or applications where noise sensitivity is a concern.- High input impedance: The Fairchild 215 C has an input impedance that is higher than 10 TΩ, which ensures that it does not load down the circuit it is connected to.- Wide input voltage range: The Fairchild 215 C can operate with input voltages ranging from -15 V to +15 V.- Low threshold voltages: The Fairchild 215 C has threshold voltages of approximately 2 V, which helps to minimize signal distortion and improve overall circuit performance.Applications for the Fairchild 215 C include:- Precision DC amplifiers- Submicron low-drift amplifiers- Wideband mixers for RF and microwave signals- Amplitude comparators, level shifters, and binary switchesOverall, the Fairchild 215 C is a reliable and high-performance JFET that is an excellent choice for a wide range of applications where low input noise, high input impedance, and wide input voltage ranges are required.
