The LT1253 is a low cost dual current feedback amplifier  
for video applications. The LT1254 is a quad version of the  
LT1253. The amplifiers are completely isolated except for  
the power supply pins and therefore have excellent isola-  
tion, over 94dB at 5MHz. Dual and quad amplifiers signifi-  
cantly reduce costs compared with singles; the number of  
insertions is reduced and fewer supply bypass capacitors  
are required. In addition, these duals and quads cost less  
per amplifier than single video amplifiers.  
O U  
The LT1253/LT1254 amplifiers are ideal for driving low  
impedance loads such as cables and filters. The wide  
bandwidth and high slew rate of these amplifiers make  
driving RGB signals between PCs and workstations easy.  
The excellent linearity of these amplifiers makes them  
ideal for composite video.

The LT1253 is available in 8-pin DIPs and the S8 surface  
mount package. The LT1254 is available in 14-pin DIPs  
and the S14 surface mount package. Both parts have the  
industry standard dual and quad op amp pin out. For  
higher performance, see the LT1229/LT1230.
