LF347 Quad J-FET Operational Amplifier IC SMDThe LF347 Quad J FET Operational Amplifier are high speed JFET input quad operational amplifiers incorporating well matched, high voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high slew rates, low input bias and offset currents, and low offset voltage temperature coefficient. Features Low power consumption Wide common mode (up to VCC+) and differential voltage range Low input bias and offset current

These are Carbon Film Resistor with a value of 15 ohm 1/4W and tolerance of ±5%
