EL2228C - Preliminary
Dual Low Noise Amplifier
Features
General Description
• Voltage noise of only 4.9nV/ÖHz
• Current noise of only 1.2pA/ÖHz
• Bandwidth (-3dB) of 80MHz -
@AV = +1
The EL2228C is a dual, low-noise amplifier, ideally suited to filtering
applications in ADSL and HDSLII designs. It feature low noise speci-
fication of just 4.9nV/ÖHz and 1.2pA/ÖHz, making it ideal for
processing low voltage waveforms.
• Gain-of-1 stable
The EL2228C has a -3dB bandwidth of 80MHz and is gain-of-1 sta-
ble. It also affords minimal power dissipation with a supply current of
just 4.5mA per amplifier. The amplifier can be powered from supplies
ranging from ±2.5V to ±12V.
• Just 4.5mA per amplifier
• 8-pin MSOP package
• ±2.5V to ±12V operation
The EL2228C is available in a space saving 8-Pin MSOP package as
well as the industry standard 8-Pin SO. It can operate over the -40°C to
+85°C temperature range.
Applications
• ADSL Filters
• HDSLII Filters
• Ultrasound input amplifiers
• Wideband Instrumentation
• Communications equipment
• Wideband sensors
