The TL07xx JFET-input operational amplifiers incorporate well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high slew rates, low-input bias and offset currents, and low offset-voltage temperature coefficient. The low harmonic distortion and low noise make the TL07x series ideally suited for high-fidelity and audio pre-amplifier applications. The TL071 device has offset pins to support external input offset correction.
The JFET-input operational amplifiers in the TL07xx series are similar to the TL08x series, with low input bias and offset currents, and a fast slew rate. The low harmonic distortion and low noise make the TL07xx 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 0°C to 70°C. The I-suffix devices are characterized for operation from −40°C to +85°C. The M-suffix devices are characterized for operation over the full military temperature range of −55°C to +125°C.
Harmonic distortions to an audio signal are created by electronic components in a circuit. Total harmonic distortion (THD) is a measure of harmonic distortions accumulated by a signal in an audio system. These devices have a very low THD of 0.003% meaning that the TL07x device adds little harmonic distortion when used in audio signal applications.
The slew rate is the rate at which an operational amplifier can change the output when there is a change on the input. These devices have a 13-V/μs slew rate.
These devices are powered on when the supply is connected. These devices can be operated as a single-supply operational amplifier or dual-supply amplifier depending on the application.
A typical application for an operational amplifier is an inverting amplifier. This amplifier takes a positive voltage on the input, and makes the voltage a negative voltage. In the same manner, the amplifier makes negative voltages positive.
The supply voltage must be selected so the supply voltage is larger than the input voltage range and output range. For instance, this application scales a signal of ±0.5 V to ±1.8 V. Setting the supply at ±12 V is sufficient to accommodate this application.
For best operational performance of the device, use good PCB layout practices, including:
