... HDSLII designs. With low noise specification of just 1.9nV/√Hz and 1.2pA/√Hz, the EL2227 is perfect for the detection of very low amplitude signals. The EL2227 features a -3dB bandwidth of 115MHz and is gain-of-2 stable. The EL2227 also affords minimal power dissipation with a supply current of just 4.8mA per amplifier. ...

... EL2227 have been designed so that this “extra” bandwidth in low-gain applications does not come at the expense of stability. As seen in the typical performance curves, the EL2227 in a gain of +2 only exhibit 0.5dB of peaking with a 1000Ω load. Output Drive Capability The EL2227 have been designed to drive low impedance loads. They can easily drive 6V into a 500Ω ...
