The JFET-input TL070 operational amplifier is designed as the lower-noise version of the TL080 amplifier with low input-bias and offset currents and fast slew rate. The low harmonic distortion and low noise make the TL070 ideally suited for high-fidelity and audio-preamplifier applications. This amplifier features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip. The TL070I device is characterized for operation from -40C to 85C.
