General Description
The EL400C is a wide bandwidth, fast settling monolithic amplifier
built using an advanced complementary bipolar process. This ampli-
fier 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 EL400C has a 200MHz -3dB bandwidth
(A
V
= +2), and 12ns settling to 0.05% while consuming only 15mA of
supply current.
The EL400C is an obvious high-performance solution for video distri-
bution 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 sig-
nal fidelity. D/A systems can also benefit from the EL400C, especially
if linearity and drive levels are important.
