Medium Power Differential Line Driver
Features
General Description
• Drives up to 360mA from a +15V
supply
• 16VP-P differential output drive
into 25Ω and 20VP-P differential
output drive into 100Ω
• -85dBc typical driver output
distortion at full output at 150kHz
• Low quiescent current of 3.5mA
per amplifier at ½-IS current mode
• Disable down to 1.5mA
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 thermallyenhanced 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.

Ordering Information
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.
