description

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 TL070C device is characterized for operation from 0°C to 70°C. The TL070I device is characterized for operation from ± 40°C to 85°C. The TL070M device is characterized for operation from ±55°C to 125°C.

²Stresses beyond those listed under ªabsolute maximum ratingsº may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under ªrecommended operating conditionsº 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 may 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.
