Previously we looked at the inputs, what they look like inside the amplifier, and the differences between ideal and real behaviour. This time we look at what comes out the front end of the amplifier. When hooking up a source (power supply / battery / amplifier) to a load (appliance […]

In the introductory post, a simple example was presented showing how an op-amp can be used to map a sensitive low-amplitude signal into the range expected by an ADC. Here we look at the difference between idealized and real inputs. The Allure of ‘Ideal’ On first encountering an op-amp, it […]
