INA2331AIPWT an instrumentation amplifier IC CMOS technology with the type of output rail-to-rail. INA2331AIPWT offers signal amplification with high accuracy and low noise. This INA2331AIPWT can be used directly to drive a sampling of the converter ADC, so it is ideal when applied to the thermocouple, medical devices (ECG, EEG, EMG), audio amplifiers, communication systems, and so forth.
