1 Low Power Consumption Wide Common-Mode and Differential Voltage Ranges Low Input Bias and Offset Currents Output Short-Circuit Protection Low Total Harmonic Distortion.3% Typ TL7, TL7A, TL7B, TL72 Low Noise V n = nv/ Hz Typ at f = khz High Input Impedance...JFET Input Stage Internal Frequency Compensation Latch-Up-Free Operation High Slew Rate...3 V/µs Typ Common-Mode Input Voltage Range Includes V CC+ description The JFET-input operational amplifiers in the TL7_ series are designed as low-noise versions of the TL_ series amplifiers with low input bias and offset currents and fast slew rate. The low harmonic distortion and low noise make the TL7_ series 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 C-suffix devices are characterized for operation from C to 7 C. The I-suffix devices are characterized for operation from C to 5 C. The M-suffix devices are characterized for operation over the full military temperature range of 55 C to 25 C.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES:. 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 5 V, whichever is less.. 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.
