Dual Ultra Low Noise Amplifier
Features
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.
• EL2227 upgrade replacement
• Voltage noise of only 1.3nV/√Hz
• Current noise of only 1.5pA/√Hz
• Bandwidth (-3dB) of 350MHz @ A = -1
V
The EL1516 features a -3dB bandwidth of 350MHz @ A =
V
• Bandwidth (-3dB) of 250MHz @ A = +2
V
-1 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.
• Gain-of-2 stable
• Just 5.5mA per amplifier
• 100mA I
OUT
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.
• Fast enable/disable (EL1516A only)
• 5V to 12V operation
• Pb-free available (RoHS compliant)
The EL1516 is available in space-saving 8-pin MSOP and
industry-standard 8-pin SO packages and the EL1516A is
available in a 10-pin MSOP package. All are specified for
operation over the -40°C to +85°C temperature range.
Applications
• ADSL receivers
• VDSL receivers
Pinouts
• Home PNA receivers
• Ultrasound input amplifiers
• Wideband instrumentation
• Communications equipment
• AGC & PLL active filters
• Wideband sensors
