... G = 1/2 applications, a gain of 2 can be realized by reversing the +IN/–IN and SENSE/REFERENCE connections. When configured for a gain of 1/2, the SSM2143 and SSM2142 Balanced Line Driver provide a fully integrated, unity gain solution to driving audio signals over long cable runs. For similar performance with see SSM2141 ...

... INPUT ERRORS 1 – 12k R The main dc input offset error specified for the SSM2143 is the Input Offset Voltage. The Input Bias Current and Input Offset Current are not specified as for a normal operational amplifier. Because the SSM2143 has built-in resistors, any bias current related errors are converted into offset voltage errors ...

... 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 ...
