GENERAL DESCRIPTION

The SSM2143 is an integrated differential amplifier intended to

receive balanced line inputs in audio applications requiring a

high level of immunity from common-mode noise. The device

provides a typical 90 dB of common-mode rejection (CMR),

which is achieved by laser trimming of resistances to better than

0.005%.

Additional features of the device include a slew rate of 10 V/ s

and wide bandwidth. Total harmonic distortion (THD) is less

than 0.004% over the full audio band, even while driving low

impedance loads. The SSM2143 input stage is designed to

handle input signals as large as +28 dBu at G = 1/2. Although

primarily intended for G = 1/2 applications, a gain of 2 can be

realized by reversing the +IN/–IN and SENSE/REFERENCE

connections.

When configured for a gain of 1/2, the SSM2143 and SSM2142

Balanced Line Driver provide a fully integrated, unity gain

solution to driving audio signals over long cable runs. For

similar performance with G = 1, see SSM2141.
