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.
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.
