FN7031
200MHz Current Feedback Amplifier
The EL2070 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
EL2070 has a 200MHz -3dB bandwidth (A_V = +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.
The EL2070 is an obvious high-performance solution for
video distribution and line-driving applications, especially
when its disable feature can be used for fast analog
multiplexing. Furthermore, the low 15mA supply current, and
the very low 5mA of supply current when disabled suggest
use in systems where power is critical. With differential
gain/phase of 0.02%/0.01°, guaranteed video specifications,
and a minimum 50mA output drive, performance in these
areas is assured.
The EL2070’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 EL2070, especially if linearity and drive
levels are important.
