Working Principle

The main function of the INA2180-2181EVM is to provide signal conditioning. The device is designed to provide low-power rail-to-rail IO amplification and features an internal op-amp circuit that reinforces the signal before it is presented to a voltage-leveling circuit. It is also designed with a voltage-leveling circuit to improve linearity. This ensures that the signal is accurately amplified and presented to the receiving circuit.The INA2180-2181EVM can also be used to build precision amplifiers for specific applications such as instrumentation and communications. It features a single-ended input stage that supports rail-to-rail input/output operation enabling precision interconnects. The voltage regulation in the input stage ensures high accuracy and reduces distortion, while the low voltage and low current consumption ensures efficient and reliable performance.The output stage contains a voltage-leveling circuit that offers excellent linearity in order to ensure accuracy regardless of the amplitude of the signal. The output stage also has a variable gain setting (VGS) which can be adjusted to optimize performance for a specific application. This makes the device ideal for power-efficient systems which require a combination of precision and cost-effectiveness."
