SSM2143P Datasheet

Special Purpose Amplifiers


The SSM2143P 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/µsand 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/REFERENCEconnections. SSM2143P Features • High Common-Mode Rejection DC: 90 dB typ 60 Hz: 90 dB typ 20 kHz: 85 dB typ• Ultralow THD: 0.0006% typ @ 1 kHz• Fast Slew Rate: 10 V/ s typ• Wide Bandwidth: 7 MHz typ (G = 1/2)• Two Gain Levels Available: G = 1/2 or 2• Low Cost
