EL2072
FN7033
730MHz Closed Loop Buffer
The EL2072 is a wide bandwidth, fast
settling monolithic buffer built using an
advanced complementary bipolar
process. This buffer is closed loop to achieve lower output
impedance and higher gain accuracy. Designed for closed-
loop unity gain, the EL2072 has a 730MHz -3dB bandwidth
and 5ns settling to 0.2% while consuming only 15mA of
supply current.
The EL2072 is an obvious high-performance solution for
video distribution and line-driving applications. With low
15mA supply current and a 70mA output drive, performance
in these areas is assured.
The EL2072's settling to 0.2% in 5ns, low distortion, and
ability to drive capacitive loads make it an ideal flash A/D
driver. The wide 730MHz bandwidth and extremely linear
phase allow unmatched signal fidelity.
The EL2072 can be used inside an amplifier loop or PLL as
its wide bandwidth and fast rise time have minimal effect on
loop dynamics.
Elantec products and facilities comply with MIL-I-45028A,
and other applicable quality specifications. For information
on Elantec's processing, see Elantec document QRA-1:
