This application note describes how the circuit described herein removes the requirement for additional summing amplifiers and the IOUT architecture allows both ac and dc inputs, making this circuit ...

A common PC sound card can be used as a sine/square/triangle function generator, but the output suffers from limited rail-to-rail swing, plus its zero-centered has no dc offset. This circuit overcomes ...

We all know how to block the DC offset of an AC signal — that just requires putting a capacitor in series, right? But what if the AC signal doesn’t alternate very often? In that case, things get a ...

Most strain gage measurements are plagued with offset drift and noise. This app note shows how to use an ac signal to excite the bridge, which produces a dc output proportional to the strain. To view ...

To deal with errors in your design’s analog-signal chain,you must understand their sources in attenuators, amplifiers,multiplexers, references, and ADCs. Although MonteCarlo Spice simulations can help ...
