EL2126
FN7046.1
Ultra-Low Noise, Low Power, Wideband
Amplifier
The EL2126 is an ultra-low noise,
wideband amplifier that runs on half
the supply current of competitive parts.
It is intended for use in systems such as ultrasound imaging
where a very small signal needs to be amplified by a large
amount without adding significant noise. Its low power
dissipation enables it to be packaged in the tiny SOT-23
package, which further helps systems where many input
channels create both space and power dissipation problems.
The EL2126 is stable for gains of 10 and greater and uses
traditional voltage feedback. This allows the use of reactive
elements in the feedback loop, a common requirement for
many filter topologies. It operates from ±2.5V to ±15V
supplies and is available in the 5-pin SOT-23 and 8-pin SO
packages.
The EL2126 is fabricated in Elantec’s proprietary
complementary bipolar process, and is specified for
operation over the full -40°C to +85°C temperature range.
Features
• Voltage noise of only 1.3nV/√Hz
• Current noise of only 1.2pA/√Hz
• 200µV offset voltage
• 100MHz -3dB BW for AV=10
• Very low supply current - 4.7mA
• SOT-23 package
• ±2.5V to ±15V operation
Applications
• Ultrasound input amplifiers
• Wideband instrumentation
• Communication equipment
• AGC & PLL active filters
• Wideband sensors
