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.
