8.1 Overview
The JFET-input operational amplifiers is in the TL07xx series are similar to the TL08x series, with low input bias
and offset currents and 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.
