Data Sheet

Dual Ultra Low Noise Amplifier

The EL1516 is a dual, ultra low noise amplifier, ideally suited
to line receiving applications in ADSL, VDSL, and home
PNA designs. With low noise specification of just 1.3nV/√Hz
and 1.5pA/√Hz, the EL1516 is perfect for the detection of
very low amplitude signals.

The EL1516 features a -3dB bandwidth of 350MHz @ A

=-1

V

and is gain-of-2 stable. The EL1516 also affords minimal
power dissipation with a supply current of just 5.5mA per
amplifier. The amplifier can be powered from supplies ranging
from 5V to 12V.

The EL1516A incorporates an enable and disable function to
reduce the supply current to 5nA typical per amplifier,
allowing the EN

pins to float or apply a low logic level will

enable the amplifiers.
The EL1516 is available in space-saving 8 Ld MSOP and

industry-standard 8 Ld SOIC packages and the EL1516A is
available in a 10 Ld MSOP package. All are specified for
operation over the -40°C to +85°C temperature range.
