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
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 -40C to +85C temperature
range.
The EL1507C has two control pins, C0 and C1. With the selection of
C0 and C1, the device can be set into full-I
S
power, -I
S
power, -I

power, and power down disable modes. The EL1507C maintains
excellent distortion and load driving capabilities even in the lowest
power settings.
