Many single-supply operational amplifiers are capable of rail-to-rail input operation, if they have the proper input circuitry to support this function. This article is an expansion of the blog post ...

The need for conditioning low-level ac signals in the presence of both common-mode noise and differential dc voltage prevails in many applications. In such situations, ac-coupling to instrumentation ...

Op amps played a critical role in knocking out German cruise missiles in WWII. Scientists at Bell Labs came up with a spiffy, high-gain, differencing amplifier. Andy’s still threatening to run SPICE ...
