Description

The EL400 is a wide bandwidth, fast settling monolithic amplifier 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 EL400 has a 200MHz -3dB bandwidth (A_V = +2), and 12ns settling to 0.05% while consuming only 15mA of supply current.

The EL400 is an obvious high-performance solution for video distribution and line-driving applications. With low 15mA supply current, differential gain/phase of 0.02%/0.01^o, and a minimum 50mA output drive, performance in these areas is assured.

The EL400's settling to 0.05% in 12ns, low distortion, and ability to drive capacitive loads make it an ideal flash A/D driver. The wide 200MHz bandwidth and extremely linear phase allow unmatched signal fidelity. D/A systems can also benefit from the EL400, especially if linearity and drive levels are important.
