## 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.

## LTC6363 Differential AV = 1/9 Configuration Using an LT®5400 Quad-Matched Resistor Network

Aug 31st 2015

The LTC®6363 is a low power, low noise, fully differential op amp with rail-to-rail outputs optimized to drive low power SAR ADCs. The LTC6363 draws only 1.9mA supply current in active operation and features a shutdown mode which reduces the current consumption to 20μA (VS = 3V). ...

## DC Accurate Driver for the LTC2377-20 Achieves 2ppm Linearity

Jan 10th 2014

Introduction
As resolution and sample rates continue to rise for analog-to-digital converters (ADCs), the driver circuitry for the ADC analog input, not the ADC itself, has increasingly become the limiting factor in determining overall circuit accuracy. First, the driver circuitry must buffer the input signal and provide gain. ...

## High Voltage CMOS Amplifier Enables High Impedance Sensing with a Single IC

Apr 1st 2013

Introduction
Accurately measuring voltages requires minimizing the impact of the instrument connection to the tested circuit. Typical digital voltmeters (DVMs) use 10M resistor networks to keep loading effects to an inconspicuous level, but even this can introduce significant error, particularly in higher voltage circuits that ...

## Matched Resistor Networks for Precision Amplifier Applications

May 1st 2012

Introduction
Some ideal op amp configurations assume that the feedback resistors exhibit perfect matching. In practice, resistor non-idealities can affect various circuit parameters such as common mode rejection ratio (CMRR), harmonic distortion and stability. For instance, as shown in Figure 1, a single-ended amplifier configured ...
