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
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°, 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.
