LINE DRIVER/RECEIVER SYSTEM
The SSM2143 and SSM2142 provide a fully integrated line driver/
receiver system. The SSM2142 is a high performance balanced
line driver IC that converts an unbalanced input into a balanced
output signal. It can drive large capacitive loads on long cables
making it ideal for transmitting balanced audio signals. When com-
bined with an SSM2143 on the receiving end of the cable, the sys-
tem maintains high common-mode rejection and ultralow THD.
The SSM2142 is designed with a gain of +2 and the SSM2143
with a gain of 1/2, providing an overall system gain of unity.
The following data demonstrates the typical performance of the
two parts together, measured on an Audio Precision at the
SSM2143’s output. This configuration was tested with 500 feet

of cable between the ICs as well as no cable. The combination
of the two parts results in excellent THD+N and SNR and a noise
floor of typically –105 dB over a 20 Hz to 20 kHz bandwidth.
A comment on SSM2142/SSM2143 system headroom is neces-
sary. Figure 31 shows a maximum signal handling of approximately
tween the SSM2142’s input and SSM2143’s output, which has
been attenuated by one half. Normally, the system would be shown
as actually used in a piece of equipment, whereby the SSM2143 is
at the input and SSM2142 at the output. In this case, the system
could handle differential signals in excess of +24 dBu at the input
and output, which is consistent with headroom requirements of
most professional audio equipment.
