Video Distribution Amplifier
Features
The EL8108 is a dual current feedback
operational amplifier designed for
video distribution solutions. This
• Drives up to 450mA from a +12V supply
• 20V differential output drive into 100Ω
P-P
• -85dBc typical driver output distortion at full output at
150kHz
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.
• -70dBc typical driver output distortion at 3.75MHz
• Low quiescent current of 5mA per amplifier
• 300MHz bandwidth
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.
• Pb-free available (RoHS compliant)
Applications
The EL8108 is ideal for driving multiple video loads while
maintaining linearity.
• Video distribution amplifiers
