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/μs
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.
