Operational amplifiers — or op amps, as you probably call them — have long been a key building block in analog circuits. It’s true even in our digital age as op amps are tapped to handle useful ...

In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...

An op amp-based amplifier design overcomes errors associated with resistive current sensing, particularly those resulting from high commonmode voltages. Many current-sensing ICs are available for ...
