EL5293, EL5293A
D a ta Sheet A p r il, 2003 FN7193.1
Dual 300MHz Current Feedback Amplifier with Enable
The EL5293 and EL5293A represent dual current feedback amplifiers with a bandwidth of 300MHz. This makes these amplifiers ideal for today's high speed video and monitor applications. With a supply current of just 4mA per amplifier and the ability to run from a single supply voltage from 5V to 10V, these amplifiers are also ideal for hand held, portable or battery powered equipment. The EL5293A also incorporates an enable and disable function to reduce the supply current to 100µA typical per amplifier. Allowing the CE pin to float or applying a low logic level will enable the amplifier. The EL5293 is offered in the industry-standard 8-pin SO package and the space-saving 8-pin MSOP package. The EL5293A is available in a 10-pin MSOP package and all operate over the industrial temperature range of -40°C to +85°C.
Features
· 300MHz -3dB bandwidth · 4mA supply current (per amplifier) · Single and dual supply operation, from 5V to 10V · Fast enable/disable (EL5293A only) · Single (EL5193) and triple (EL5393) available · High speed, 1GHz product available (EL5191) · High speed, 6mA, 600MHz product available (EL5192, EL5292, and EL5392)
Applications
· Battery-powered equipment · Hand-held, portable devices · Video amplifiers · Cable drivers · RGB amplifiers · Test equipment · Instrumentation

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
