GENERAL D ESCRIP TIO N

Based on a cross-coupled, electronically balanced topology, the

SSM2142 mimics the performance of fully balanced

transformer-based solutions for line driving. However, the

SSM2142 maintains lower distortion and occupies much less

board space than transformers while achieving comparable

common-mode rejection performance with reduced parts count.

T he SSM2142 is an integrated differential-output buffer

amplifier 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, the SSM2142 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.

T he carefully designed output stage of the SSM2142 is capable

of driving difficult loads, yielding low distortion performance

despite extremely long cables or loads as low as 600 Ω, and is

stable over a wide range of operating conditions.

T he SSM2142 in tandem with the SSM2141 differential

receiver establishes a complete, reliable solution for driving and

receiving audio signals over long cables. T he SSM2141 features

an Input Common-Mode Rejection Ratio of 100 dB at 60 Hz.

Specifications demonstrating the performance of this typical

system are included in the data sheet.
