General Description

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 50

Ω 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.

The EL1507C has two control pins, C0 and C1. With the selection of

power, and power down disable modes. The EL1507C maintains

excellent distortion and load driving capabilities even in the lowest

power settings.
