![]() Each of these models highlight different methods available within LTspice for use with the wide variety of component models supplied from various vendor websites. This Instructable will demonstrate how to go beyond the component library supplied with LTspice by incorporating an LMV321 op-amp model from three different chip vendors to create a simple amplifier schematic as shown in the drawing. ![]() ![]() ![]() The learning curve is easy to conquer thanks to support by Analog Devices, Yahoo's LTspice Support Group and its compatibility with most common SPICE models supplied by chip vendors. I use it to research circuit behavior and quickly experiment with new circuits for my lab before prototyping a PCB (Printed Circuit Board) design. OEMsecrets.LTspice is a free SPICE simulation software tool with schematic capture, waveform viewer, and many enhancements that runs on both Windows and Mac OS X.Blog Post: Why is it so challenging to design a voltage reference circuit for an ADC?.Low Total Harmonic Distortion: 0.003% TypicalĦ. Wide Common-Mode and Differential Voltage Rangesĥ. Offset adjustment and external compensation options are available within the TL07x family.Ģ. The low harmonic distortion and low noise make the TL072 series ideally suited for high-fidelity and audio pre-amplifier applications. The devices feature high slew rates, low-input bias and offset currents, and low offset-voltage temperature coefficient. Each of these JFET-input operational amplifiers incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The TL072 JFET-input operational amplifier family is designed to offer a wider selection than any previously developed operational amplifier family. ![]()
