The EL5178 and EL5378 are single and triple high bandwidth

amplifiers with an output in differential form. They are

primarily targeted for applications such as driving twisted-pair

lines in component video applications. The inputs can be in

either single-ended or differential form but the outputs are

always in differential form.

On the EL5178 and EL5378, two feedback inputs provide the

user with the ability to set the gain of each device (stable at

minimum gain of 2).

The output common mode level for each channel is set by the

associated REF pin, which has a -3dB bandwidth of over

110MHz. Generally, these pins are grounded but can be tied to

any voltage reference.

All outputs are short circuit protected to withstand temporary

overload condition.

The EL5178 is available in 8 Ld MSOP and SOIC packages and

EL5378 is available in a 28 Ld QSOP package. All are specified

for operation over the full -40°C to +85°C temperature range.
