EL5367
1GHz Triple Current Feedback Amplifier
The EL5367 triple amplifier is of the current feedback variety
and exhibits a very high bandwidth of 1GHz at A
V
= +1 and
800MHz at A
V
= +2. This makes this amplifier ideal for
today's high speed video and monitor applications, as well
as a number of RF and IF frequency designs.
With a total supply current of just 25mA and the ability to run
from a single supply voltage from 5V to 12V, this amplifier
offers very high performance for little power consumption.
The EL5367 is available in a 16-pin QSOP package and is
specified for operation over the full -40C to +85C
temperature range.
