EL1509C - Product Brief
Medium Power Differential Line Driver
Features
General Description
• Drives up to 250mA from a +12V
supply
• 20VP-P differential output drive
into 100W
• -85dBc typical driver output
distortion at full output at 150kHz
• Low quiescent current of 7.5mA
per amplifier
The EL1509C is a dual operational amplifier designed for customer
premise line driving in DMT ADSL solutions. This device features a
high drive capability of 250mA while consuming only 7.1mA of sup-
ply current per amplifier and operating from a single 5V to 12V
supply. This driver achieves a typical distortion of less than -85dBc, at
150kHz into a 25W load. The EL1509C is available in the industry
standard 8-pin SO as well as the thermally-enhanced 8-pin LPP pack-
age. Both are specified for operation over the full -40°C to +85°C
temperature range.
Applications
The EL1509C is ideal for ADSL, SDSL, HDSL2 and VDSL line driv-
ing applications.
• ADSL G.lite CO line driving
• ADSL full rate CPE line driving
• G.SHDSL, HDSL2 line driver
• Video distribution amplifier
• Video twisted-pair line driver
