DESCRIPTION
The TS616 is a dual operational amplifier featur-
ing a high output current of 410mA. The drivers
can be configured differentially for driving signals
in telecommunication systems using multiple car-
riers. The TS616 is ideally suited for xDSL (High
Speed Asymmetrical Digital Subscriber Line) ap-
plications. This circuit is capable of driving a 10
or 25
load at
2.5V, 5V,
6V or +12V power
supply. The TS616 is able to reach a -3dB band-
width of 40MHz on 25
load with a 12dB gain.
This device is designed for high slew rates sup-
porting low harmonic distortion and intermodula-
tion.

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
CC
+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.

Note: As described on page 24 (table 71), the TS616 requires a 620
feedback resistor for an optimized bandwidth with a gain of 12B for
a 12V power supply. Nevertheless, due to production test constraints, the TS616 is tested with the same feedback resistor for 12V and 5V
power supplies (910
