When a fixed-gain amplifier doesn’t offer the optimum gain for your application, you can adjust the gain to a lower value by adding an external resistor network. This attenuation circuit works like a ...

When available fixed-gain values match design requirements, a PGA (programmable-gain-amplifier) IC offers a drop-in choice, but what does a designer do when a suitable PGA is unavailable? Before the ...

Most everyone that has ever purchased an external amplifier is at least familiar with the term voltage gain. Simply, it is the degree to which an amplifier actually ...
