Description
The TS615 is a dual operational amplifier
featuring a high output current of 410 mA. This
driver 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
capable of driving a 10 Ω or 25 Ω load on a range
of power supplies: ±2.5 V, 5 V, ±6 V or +12 V. The
TS615 is capable of reaching a -3 dB bandwidth
of 40 MHz on a 25 Ω load with a 12 dB gain. This
device is designed for high slew rates and
demonstrates low harmonic distortion and
intermodulation. The TS615 offers a power-down
function to order to decrease power consumption.
During sleep mode, the device short circuits its
output in order to keep the impedance matched to
the line. The TS615 is housed in TSSOP14
exposed-pad plastic package for a very low
thermal resistance.
