Operational amplifier (op-amp)

noreply@blogger.com (Anonymous) — Thu, 25 Jul 2013 06:08:00 -0700

An operational amplifier (op-amp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. In this configuration, an op-amp produces an output potential (relative to circuit ground) that is typically hundreds of thousands of times larger than the potential difference between its input
