PRELIMINARY

EL8108

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-pin SO as

well as the thermally-enhanced 16-pin 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.

Features

• Drives up to 450mA from a +12V supply

• -85dBc typical driver output distortion at full output at

150kHz

• -70dBc typical driver output distortion at 3.75MHz

• Low quiescent current of 5mA per amplifier

• 300MHz bandwidth

Applications

• Video distribution amplifiers
