The SSM2142 is an integrated differential-output bufferamplifier that converts a single-ended input signal to a balancedoutput signal pair with high output drive. By utilizing low noisethermally matched thin film resistors and high slew rateamplifiers, the SSM2142 helps maintain the sonic quality ofaudio systems by eliminating power line hum, RF interference,voltage drops, and other externally generated noise commonlyencountered with long audio cable runs. Excellent rejection ofcommon-mode noise and offset errors is achieved by lasertrimming of the onboard resistors, assuring high gain accuracy.The carefully designed output stage of the SSM2142 is capableof driving difficult loads, yielding low distortion performancedespite extremely long cables or loads as low as 600 W, and isstable over a wide range of operating conditions.
