DESCRIPTION
The TS615 is a dual operational am plifier featur­ing a high output current 410mA. These drivers can be configured differentially for driving signals in telecommunication systems using multiple car­riers. The TS615 is ideally suited for xDSL (High Speed Asymmetrical Digital Subscriber Line) ap­plications. This circuit is c apable of driving a 10 or 25 load at ±2.5V, 5V, ±6V or +12V power supply. The TS615 will be able to reach a -3dB bandwidth of 40MHz on 25 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.

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 V
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.

Note: as described on page 24 (table 71), the TS615 requires a 620Ω feedback res i st or for an optimis ed bandwidth wi t h a gai n of 12 B for a 12V power supply. Nevertheless, due to production test constraints, the TS615 is tested with the same feedback resistor for 12V and 5V power su ppl i es (910Ω).
