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 25Ω load. The EL1511 is available in the thermallyenhanced 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.

The EL1511 has two control pins, C0 and C1, which allow the selection of full IS power, 3/4-IS, 1/2-IS, and power-down 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.
