The low harmonic distortion and low noise make the TL074x2 ideally suited for high-fidelity and audio-preamplifier applications. Each amplifier features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip. The TL074x2 is characterized for operation from 0C to 70C.

These are stress ratings only, and functional operation of the device at these conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC - . 2. Differential voltages are at IN + with respect to IN -. 3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less. 4. The output can be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded.
