General Description

The EL1511C is a dual operational amplifier designed for customer
premise line driving in DMT ADSL solutions. This device features a
high drive capability of 360mA while consuming only 7.5mA of sup­ply current per amplifier and operating from a single 5V to 15V
supply. This driver achieves a typical distortion of less than -85dBc, at

150kHz into a 25Ω load. The EL1511C is available in the thermally-

enhanced 16-pin SO (0.150") and a 16-pin LPP (4x4mm) packages.
The EL1511C is specified for operation over the full -40°C to +85°C
temperature range. Electrical characteristics are given for typical 12V
supply operation.

The EL1511C has two control pins, C0 and C1, which allow the selec­tion of full IS power, ¾-IS, ½-IS, and power-down modes.

The EL1511C is ideal for ADSL, SDSL, and HDSL2 line driving
applications for single power supply, high voltage swing, and low
power.

The EL1511C maintains excellent distortion and load driving capabil­ities even in the lowest power settings.
