DESCRIPTIO

The LT1252 is a low cost current feedback amplifier for

video applications. The LT1252 is ideal for driving low

impedance loads such as cables and filters. The wide

bandwidth and high slew rate of this amplifier make

driving RGB signals between PCs and workstations easy.

The linearity of the LT1252 is outstanding; it is unsur-

passed for driving composite video.

The LT1252 is available in the 8-pin DIP and the S8 surface

mount package. For higher performance and shutdown

operation, see the LT1227. For dual and quad amplifiers

with similar performance see the LT1253/LT1254.
