## LTspice: Worst-Case Circuit Analysis with Minimal Simulations Runs

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.

## Hybrid Wide Dimming Ratio Linear LED Current Controller Using LT8614 & LT3083/LT6015

Oct 17th 2016

Many applications for LED illumination require wide dimming ratios. This can be accomplished simply via an adjustable current source as show below. The current source can be varied by a number of different means, and a large LED current range can be achieved. The primary problem with this technique is that the power dissipation ...

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

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

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 ...

## Positive to Negative Converter with Variable Output Using LTC3630 and LT6015/LT6016

Sep 1st 2015

There was a window of time in the 1950s and early ’60s when negative voltage rails were commonplace, when germanium PNP transistors were prevalent—like those used in an old “transistor radio”, now worth a fortune on Ebay. Nowadays, NPN transistors are more prevalent, since they basically work ...

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

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

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 ...
