T he 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. T he 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
40 dB of CMR—inadequate for high-performance audio.

T he SSM2141 achieves low distortion performance by
maintaining a large slew rate of 9.5 V/µs and high open-loop
gain. Distortion is less than 0.002% over the full audio
bandwidth. T he SSM2141 complements the SSM2142
balanced line driver. T ogether, these devices comprise a fully
integrated solution for equivalent transformer balancing of
audio signals without the problems of distortion, EMI fields,
and high cost.
Additional applications for the SSM2141 include summing
signals, differential preamplifiers, and 600 Ω low distortion
buffer amplifiers. For similar performance with G = 1/2, see
SSM2143.

AP P LICATIO NS INFO RMATIO N
T he 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 µF capacitor located within
close proximity from each supply pin to ground.

MAINTAINING CO MMO N-MO D E REJECTIO N
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 Ω imbalance will
degrade CMR by 20 dB. Also, the matching of the reactive
source impedance must be matched in order to preserve the
CMRR over frequency.
