1 / 19 page  FN7046 Rev 4.00 Page 1 of 19 May 2, 2007 FN7046 Rev 4.00 May 2, 2007 EL2126 Ultra-Low Noise, Low Power, Wideband Amplifier DATASHEET 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.
