The drivers can be configured differentially for driving signals in telecommunication systems using multiple carriers. The TS616 is ideally suited for xDSL (High Speed Asymmetrical Digital Subscriber Line) applications. This circuit is capable of driving a 10 Ω or 25 Ω load at ±2.5V, 5V, ±6V or +12V power supply. The TS616 is able to reach a -3dB bandwidth of 40MHz on 25Ω load with a 12dB gain. This device is designed for high slew rates supporting low harmonic distortion and intermodulation.

All voltage values, except differential voltage are with respect to network terminal. Differential voltage are non-inverting input terminal with respect to the inverting input terminal. The magnitude of input and output voltage must never exceed VCC +0.3V. An output current limitation protects the circuit from transient currents. Short-circuits can cause excessive heating. Destructive dissipation can result from short circuit on amplifiers.

Nevertheless, due to production test constraints, the TS616 is tested with the same feedback resistor for 12V and 5V power supplies (910Ω).
