Amplifier arrangement and communication line circuit using same |
| abstract |
The line circuit includes an amplifier arrangement with two amplifiers (LOA1/2) each able to sink current from an associated line conductor (L1/2) to a negative voltage (V-) and via a common transistor (T). Each amplifier has an individual overcurrent detection circuit (OCD1/2) and a individual current limiting circuit (CLC1/2). The detection circuits are coupled to the limiting circuits through a common detection circuit (OCD3) and a common gating circuit (GCI) which supplies an active output signal to the limiting circuits when both the amplifiers sink excessive currents. |
