Working Principles

LMV797MM operates based on the principles of operational amplifiers. It utilizes a differential input stage, followed by gain stages and an output buffer. The differential input stage amplifies the voltage difference between the non-inverting and inverting inputs, while subsequent gain stages provide additional amplification. The output buffer ensures that the amplified signal is delivered to the load with minimal distortion.
