EL1507C - Product Brief
Medium Power Differential Line Driver
Features
General Description
• Drives 360mA at 16VP-P on ±12V
supplies
• 40VP-P differential output drive
The EL1507C is a very low power dual operational amplifier designed
for central office and customer premise line driving for DMT ADSL
solutions. This device features a high drive capability of 400mA while
consuming only 7.5mA of supply current per amplifier from ±12V
supplies. This driver achieves a typical distortion of less than -75dBc,
at 1MHz into a 50W load. The EL1507C is available in the thermally-
enhanced 16-pin SO package, as well as a 16-pin LPP package. Both
are specified for operation over the full -40°C to +85°C temperature
range.
into 100W
• -75dBc typical driver output
distortion driving 50W at 1MHz
and ½-IS bias current
• Low quiescent current of 3.5mA
per amplifier in ½-IS mode
• Power down disable mode
The EL1507C has two control pins, C0 and C1. With the selection of
C0 and C1, the device can be set into full-IS power, ¾-IS power, ½-IS
power, and power down disable modes. The EL1507C maintains
excellent distortion and load driving capabilities even in the lowest
power settings.
Applications
• ADSL G.DMT and G.lite CO line
driving
• G.SHDSL, HDSL2 line driver
• ADSL CPE line driving
• Video distribution amplifier
• Video twisted-pair line driver
