ELANTEC EL1511CL

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.
Applications
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.
ADSL CSA line driving
ADSL full rate CPE line driving
G.SHDSL, HDSL2 line driver
Video distribution amplifier
Video twisted-pair line driver
Ordering Information
The EL1511C maintains excellent distortion and load driving capabilities even in the lowest power settings.
