The INA2143UE4 consists of two input buffers, two input transistors, two output transistors, two feedback transistors, and two gain setting resistors. The input transistors receive the two input signals, amplify them, and then output the amplified signals to the output transistors. The output transistors then amplify the input signals and output the amplified signals to the two feedback transistors. The feedback transistors enable the gain of the amplifier to be adjusted through the two gain setting resistors. The gain setting resistors allow the output signal to be adjusted to the desired level.

In conclusion, INA2143UE4 is a high-performance buffering application with low noise and high input impedance. It is used in medical instruments, test and measurement equipment, audio equipment, power supplies, robotics, and communication systems. Its working principle is based on the concept of an operational amplifier, where two input signals are amplified and the gain can be adjusted through the two gain setting resistors.
