Low Power Precision Op Amp Allows Fast, Accurate Multiplexing

Kris Lokere - Strategic Applications Manager Nov 19th 2014
If you need to measure many analog voltages, but not necessarily all at the same time, then a common approach is to multiplex these signals together into one output signal, so that you can then process and digitize each of these original voltage levels one at a time using shared circuitry. But doing this right requires some ...

Paralleling Amplifiers and Layout Essentials for Driving Capacitive Loads Fast - LT1397, LT1206, LT1207

Glen Brisebois - Applications Engineer - Signal Conditioning Dec 15th 2008
Certain video and other technologies require driving planar conductive surfaces fast. Unfortunately, the surfaces can have high capacitance, which means that driving them fast takes high currents. This complicates the amplifier design but the situation extends beyond just the amplifier. Between the amplifier and the capacitive ...

Build Your Own Laboratory Precision Voltage Source - LT1236, LT1881, LT1010, LT1017

Mark Thoren - Staff Scientist Jun 15th 2008
Every electronics lab needs a couple different types of voltage sources. Power supplies are the obvious choice, but these bench top supplies are not very stable over time and temperature, they cannot sink current and it can be very difficult to set an accurate voltage. This video gives a step-by-step demonstration of an amplifier ...
