General Description

The EL2070C is a wide bandwidth, fast settling monolithic amplifier incorporating a disable/enable feature. Built using an advanced complementary bipolar process, this amplifier uses current-mode feedback to achieve more bandwidth at a given gain than conventional operational amplifiers. Designed for closed-loop gains of ±1 to ±8, the EL2070C has a 200MHz -3dB bandwidth (AV = +2), and 12ns settling to 0.05 while consuming only 15mA of supply current. Furthermore, the fast disable/enable times of 200ns/100ns allow rapid analog multiplexing.
