LT1254CS#PBF

LT1254CS#PBF is a low-cost quad-current feedback amplifier for video applications. This amplifier is completely isolated except for the power supply pins and therefore has excellent isolation, over 94dB at 5MHz. The quad amplifiers significantly reduce costs compared with singles; the number of insertions is reduced and fewer supply bypass capacitors are required. This amplifier 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 excellent linearity of this amplifier makes it ideal for composite video. It is used in applications such as RGB cable drivers, composite video cable drivers, and gain blocks in IF stages.
