TL062放大器 运算 低功耗

描述

The JFET-input operational amplifiers of the TL06x series are designed as low-power versions of the TL08x series amplifiers. They feature high input impedance, wide bandwidth, high slew rate, and low input offset and input bias currents. The TL06x series features the same terminal assignments as the TL07x and TL08x series.

With enough feedback, the closed loop amplifier characteristics become a function of the

feedback elements. In the typical feedback circuit, figure 1, the feedback elements are two

resistors. The precision of the “closed loop” gain is set by the ratio of the two resistors and is

practically independent of the “open loop” amplifier. Thus, amplification to almost any degree of

precision can be achieved with ease.

Notation and Terminology

Texas Instruments employs the industry standard operational amplifier symbols shown in figure

2. Power pins are often omitted from the schematic symbol when the power supply voltages are

explicit elsewhere in the schematic. Some op amp symbols also include offset nulling pins,

enable / disable pins, output voltage threshold inputs, and other specialized functions.
