General Description

The EL2070C is a wide bandwidth, fast settling monolithic amplifier

incorporating a disable/enable feature. Built using an advanced com-

plementary bipolar process, this amplifier uses current-mode feedback

to achieve more bandwidth at a given gain than conventional opera-

tional amplifiers. Designed for closed-loop gains of ±1 to ±8, the

to 0.05% while consuming only 15mA of supply current. Furthermore,

the fast disable/enable times of 200ns/100ns allow rapid analog

multiplexing.

The EL2070C is an obvious high-performance solution for video dis-

tribution 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 differen-

tial gain/phase of 0.02%/0.01°, guaranteed video specifications, and a

minimum 50mA output drive, performance in these areas is assured.

The EL2070C'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 EL2070C,

especially if linearity and drive levels are important.
