Differential Amplifiers
Differential amplifiers from Analog Devices are highly integrated and optimized for differential signaling applications. These devices have inherent common-mode rejection properties, provide low harmonic distortion, and have excellent output gain and phase matching. Whether you’re driving or receiving signals over long cable lengths, driving a balanced ADC input, or looking for complementary outputs, ADI has the differential amplifiers to meet your needs.
