EL2126C

EL2126C - Preliminary EL2126C - Preliminary Ultra-low Noise, Low Power, Wideband Amplifier Features Voltage noise of only 1.3nV/√Hz Current noise of only 1.2pA/√Hz Low offset voltage ≤200µV 90MHz -3dB BW for AV=10 Very low supply current -4.7mA SOT23 package ±5V to ±15V operation General Description The EL2126C 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 SOT23 package, which further helps systems where many input channels create both space and power dissipation problems. The EL2126C 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 ±5V to ±15V supplies and is available in a 5-pin SOT23 package and 8-pin SO and 8-pin PDIP packages. The EL2126C is fabricated in Elantec’s proprietary complementary bipolar process, and is specified for operation over the full -40°C to +85°C temperature range.
