... Line Receivers Summing Amplifiers Buffer Amplifiers–Drives 600 GENERAL DESCRIPTION The SSM2141 is an integrated differential amplifier intended to receive balanced line inputs in audio applications requiring a high level of noise immunity and optimum common-mode rejection. The SSM2141 typically achieves 100 dB of common- mode rejection (CMR), whereas implementing an op amp with four off-the-shelf precision resistors will typically achieve only CMR— ...

... THEREFORE, VERTICAL SCALE = 10µV/DIV. Voltage Noise from 0 kHz to 1 kHz APPLICATIONS INFORMATION The SSM2141 represents a versatile analog building block. In order to capitalize on fast settling time, high slew rate, and high CMR, proper decoupling and grounding techniques must be employed. For decoupling, place 0.1 F capacitor located within close proximity from each supply pin to ground ...

... SSM2141 MAINTAINING COMMON-MODE REJECTION In order to achieve the full common-mode rejection capability of the SSM2141, the source impedance must be carefully controlled. Slight imbalances of the source resistance will result in a degradation of DC CMR—even a 5 degrade CMR by 20 dB. Also, the matching of the reactive source impedance must be matched in order to preserve the CMRR over frequency ...
