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. The wide 150MHz bandwidth and extremely linear phase (0.2dB deviation from linear at 50MHz) allow superior signal fidelity. These features make the EL2071 and EL2171 especially suited for many digital communication system applications. The EL2071's and EL2171's settling to 0.1% in 10ns and ability to drive capacitive loads make them ideal in flash A/D applications. D/A systems can also benefit from the EL2071 and EL2171, especially if linearity and drive levels are important.
