Description

The SSM2143PZ 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 90dB 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 10V/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 28dBu at G = 1/2. When configured for a gain of 1/2, the SSM2143 balanced line driver provides a fully integrated, unity gain solution to driving audio signals over long cable runs.
High common-mode rejection ratio
10V/ms Typical fast slew rate
0.0006% Typical at 1kHz ultra-low THD
