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

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.
