The working principle of OPA656U/2K5 is based on the principle of feedback. The device consists of two transistors, one input transistor and one output transistor connected to each other with a feedback network. The input signal is applied to the input transistor, which is then amplified and applied to the output transistor. The output transistor is then connected back to the input transistor, creating a feedback loop. The feedback loop amplifies the input signal and the output signal is then fed back to the input circuitry, creating an amplified signal.

The performance of the OPA656U/2K5 is largely determined by its input bias current. The input bias current is the amount of current that is generated from the input signal and is then applied to the output transistor. This current directly affects the gain of the amplifier and is responsible for the low noise and high linearity performance of the OPA656U/2K5. The input bias current is also responsible for the device\'s ability to operate with lower distortion and lower distortion at low frequencies.
