LTspice: Worst-Case Circuit Analysis with Minimal Simulations Runs

Joseph Spencer - Field Applications Engineer
Gabino Alonso - Strategic Marketing Engineer
Jun 8th 2017
When designing a circuit in LTspice, you may wish to assess the impact of component tolerances. For example, the gain error introduced by non-ideal resistors in an op amp circuit. This article illustrates a method that reduces the number of simulations needed, and as a result speeds your time to results. Varying a Parameter LTSpice ...

Op Amp Precision Positive & Negative Clipper using LT6015/LT6016/LT6017

Tom Mosteller - Field Applications Engineer
Aaron Schultz - Applications Manager Signal Conditioning
Oct 3rd 2016
It can be a challenge to match the voltage range of an analog signal to the input range of an analog to digital converter (ADC). Exceeding the ADC’s input range will give an incorrect reading, and if the input goes far enough beyond the power supply rails substrate currents can flow into the ADC which can cause latch up ...

Low Power, Precision Op Amp Simplifies Driving of MUXed ADCs

Guy Hoover - Applications Engineer Oct 2nd 2015
Design Note 1034: Introduction The high speed op amps required to buffer a modern 16‑/18-bit analog-to-digital converter (ADC) typically dissipate as much power as the ADC itself, often with a maximum offset spec of about 1mV, well beyond that of the ADC. If multiple multichannel ADCs are required, the power dissipation can ...

Robust High Voltage Over-The-Top Op Amps Maintain High Input Impedance with Inputs Driven Apart or When Powered Down

Glen Brisebois - Applications Engineer - Signal Conditioning Nov 5th 2014
Introduction Linear Technology’s Over-The-Top op amps have an input stage topology that allows them to operate closed loop well above the positive supply rail. The inputs remain high impedance when split apart in voltage and also when shut down or with complete loss of power supply. They are indispensable in robust ...

LTspice: Stability of Op Amp Circuits

Kris Lokere - Strategic Applications Manager Nov 6th 2013
We all know that feedback circuits can oscillate. We may even know some tricks of how to fix it. But wouldn’t it be nice if our simulation tool could show us exactly what is happening, and why? This video illustrates how to use the .AC analysis to look at open loop gain and phase of operational amplifier feedback circuits ...
