Description

Datasheet
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 Ld SOT-23 and 8 Ld 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.

... It is important to note that the extra bandwidth at lower gain does not come at the expenses of stability. Even though the EL2126 is designed for gain ≥ 10. With external compensation, the device can also operate at lower gain settings. The RC network shown in Figure 50 reduces the feedback gain at high frequency and thus maintains the amplifier stability ...

... The EL2126 has an input voltage range of 0.4V from the negative supply to 1.2V from the positive supply. So, for example single +5V supply, the EL2126 has an input voltage range which spans from 0.4V to 3.8V. The output range of the EL2126 is also quite large +5V supply, it swings from 0.4V to 3.8V. +) and pin will suffice. ...
