EL8108
FN7417.2
Video Distribution Amplifier
The EL8108 is a dual current feedback
operational amplifier designed for
video distribution solutions. This
device features a high drive capability of 450mA while
consuming only 5mA of supply current per amplifier and
operating from a single 5V to 12V supply.
The EL8108 is available in the industry standard 8 Ld SOIC
as well as the thermally-enhanced 16 Ld QFN package. Both
are specified for operation over the full -40°C to +85°C
temperature range. The EL8108 has control pins C0 and C1
for controlling the bias and enable/disable of the outputs.
The EL8108 is ideal for driving multiple video loads while
maintaining linearity.
