Analog Devices SSM2142 Balanced Line Driver Datasheet
The Analog Devices SSM2142 is an integrated differential-output buffer amplifier that converts a single-ended input signal to a balanced output signal pair. It utilizes low noise thermally matched thin film resistors and high slew rate amplifiers to maintain sonic quality in audio systems by eliminating power line hum, RF interference, and voltage drops commonly encountered with long cable runs.
The device mimics the performance of fully balanced transformer-based solutions for line driving while occupying less board space and achieving comparable common-mode rejection. It is capable of driving difficult loads, including those as low as 600 Ω, yielding low distortion performance despite extremely long cables.
