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