General Description
The EL5191C amplifier is of the current feedback variety and exhibits
a very high bandwidth of 1GHz. This makes this amplifier ideal for
today’s high speed video and monitor applications, as well as a number of RF and IF frequen cy designs.
With a supply current of just 9mA and the ability to run from a single
supply voltage from 5V to 10V, these amplifiers offer very high performance for little power consumption.
For applications where board space is critical, the EL5191C is offered
in the 5-pin SOT23 package, as well as an industry standard 8-pin SO.
The EL5191C operates over the industrial temperature range of -40°C
to +85°C.
