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 ...

All operational amplifier (op-amp) datasheets have an input voltage range limitation called the common-mode range. Strictly speaking, the common-mode voltage is the average voltage on the two inputs ...

A high-side current-sense amplifier must be protected against reversed battery connections or inductive kickbacks or other negative-voltage transient. This Idea for Design describes a circuit using ...
