The TL072SG-13 is a low noise dual JFET-input Operational Amplifier features fast slew rate, low input bias and offset currents. The low harmonic distortion and low noise make the TL072 ideally suited for high-fidelity and audio preamplifier applications. It features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip.
