EL1511

Medium Power Differential Line Driver

The EL1511 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 25

Ω load. The EL1511 is available in the thermally-

enhanced 16 Ld SOIC (0.150") and a 16 Ld QFN (4x4mm)

packages. The EL1511 is specified for operation over the full

-40°C to +85°C temperature range. Electrical characteristics

are given for typical 15V supply operation.

modes.

The EL1511 is ideal for ADSL, SDSL, and HDSL2 line

driving applications for single power supply, high voltage

swing, and low power.

The EL1511 maintains excellent distortion and load driving

capabilities even in the lowest power settings.
