Working Principle

The OPA2355DGSA/250 is a differential video amplifier module. It amplifies the video signal by using a pair of MOSFET transistors to perform an input differential conversion. This is known as a transconductance amplifier and operates by varying the current through the transistor in response to the input voltage. This type of amplifier is known for its low noise, high linearity, and wide dynamic range. When a signal is applied to the input, the two transistors enable current to flow through the load. This current is proportional to the product of the input voltage and the transconductance gain. The output voltage, then, is proportional to the current through the load and, in turn, to the input voltage.
