Working Principle

A differential input voltage is applied to the inputs of the MC33078DGKR (pins 1 and 8). The current flowing into the input pins causes the inverting and non-inverting amplifiers (pins 4 and 7) to create an output voltage. The output voltage is proportional to the differential voltage applied to the inputs. In other words, the MC33078DGKR amplifies the input signals.

The MC33078DGKR has a wide operating voltage range, from 3V to 18V, and it delivers an output voltage that is within 6.0 V of the power supply rails (between 3V and 12V). The device is also capable of delivering a low distortion output voltage (typically 0.002 % maximum) and a low noise floor (typically -100dBV). It also has a high slew rate, of 5V per �s, allowing it to accurately track dynamic signals.

The MC33078DGKR also has a number of protection features, including: over-temperature protection, short-circuit protection and lack-of-current protection. It is also capable of performing power-down sequencing, allowing it to operate safely when the supply voltage is dropped.

The MC33078DGKR is an excellent choice for a wide range of applications. Its features, such as its low noise, low distortion, wide operating voltage range and integrated protection features, make it an ideal choice for instrumentation, data acquisition, audio, and switching applications.
