The TS615 is a dual operational amplifier featuring a high output current 410mA. These drivers can be configured differentially for driving signals in elecommunication systems using multiple carriers. The TS615 is ideally suited for xDSL (High Speed Asymmetrical Digital Subscriber Line) applications. This circuit is capable of driving a 10 or 25W load at ±2.5V, 5V, ±6V or +12V power supply. The TS615 will be able to reach a -3dB bandwidth of 40MHz on 25W load with a 12dB gain. This device is designed for the high slew rates to support low harmonic distortion and intermodulation. The TS615 is fitted out with Power Down function to decrease the consumption. During this sleep state the device displays a short circuit output in order to keep the impedance matching with the line. The TS615 is housed in TSSOP14 Exposed-Pad plastic package for a very low thermal resistance.

Output Short Circuit Duration
4)
1. All voltage values, except differential voltage are with respect to network terminal. 2. Differential voltage are non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of input and output voltage must never exceed VCC +0.3V. 4. 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.
