The EL2071 and EL2171 are wide bandwidth, fast settling monolithic amplifiers built using an advanced complementary bipolar process. The EL2071 has a disable/enable feature which allows power down and analog multiplexing. These amplifiers use current-mode feedback to achieve more bandwidth at a given gain than conventional operational amplifiers. Designed for closed-loop gains of ±7 to ±50, the EL2071 and EL2171 have a 150MHz - 3dB bandwidth (AV = +20), and 2.5ns rise/fall time, while consuming only 15mA of supply current. The EL2071 consumes only 1.5mA when disabled.
