ADI SSM2142SZ

АудиоДифференциальный

Overview

The SSM2142SZ is a Balanced Line Driver that converts a single-ended input signal to a balanced output signal pair with high output drive. By utilizing low noise thermally matched thin film resistors and high slew rate amplifiers, it helps maintain the sonic quality of audio systems by eliminating power line hum, RF interference, voltage drops and other externally generated noise commonly encountered with long audio cable runs. Excellent rejection of common-mode noise and offset errors is achieved by laser trimming of the onboard resistors, assuring high gain accuracy. The carefully designed output stage of the SSM2142SZ is capable of driving difficult loads, yielding low distortion performance despite extremely long cables or loads as low as 600R and is stable over a wide range of operating conditions. Based on a cross-coupled, electronically balanced topology, the SSM2142SZ mimics the performance of fully balanced transformer-based solutions for line driving.
