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