EL400

200MHz Current Feedback Amplifier

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

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°, 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.
