TI’s TL081 is a High Slew Rate JFET-Input Operational Amplifier. Find parameters, ordering and quality information. A junction field-effect transistor (JFET) is a simple FET with a PN junction in which output current is controlled by an input voltage. The two types of JFETs include the N-channel and P-channel. A JFET, like all FETs, contains a gate (G), drain (D), and source (S). TI’s TL072 is a Dual Low-Noise JFET-Input General-Purpose Operational Amplifier. Find parameters, ordering and quality information. JFET stands for junction-gate field-effect transistor. Formerly, when one simply said 'FET,' one meant a JFET. Key features of JFETs include a large input impedance and low noise, making them suitable for impedance conversion and low-noise amplifier applications. A JFET can also be used as a simple constant-current source.
