LT1257CS8

The LT1257CS8 is designed as one kind of low cost current feedback amplifier for video applications.It 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.It can be used in RGB cable drivers,composite video cable drivers and gain blocks in IF stages.

Features of the LT1257CS8 are:(1)current feedback amplifier;(2)low cost;(3)differential gain:0.01%, RL=150W, VS=±5V;(4)differential phase:0.09°,RL=150 W,VS=±5V;(5)flat to 30MHz, 0.1dB;(6)100MHz bandwidth on ±5V;(7)wide supply range:±2V(4V) to ±14V(28V);(8)low power:85mW at ±5V.

The absolute maximum ratings of the LT1257CS8 can be summarized as:(1)total supply voltage (V+ to V-):28V;(2)input current:±15mA;(3)output short-circuit duration:continuous;(4)operating temperature range:0°C to 70°C;(5)storage temperature range:-65°C to 150°C;(6)junction temperature:150°C;(7)lead temperature (soldering, 10 sec):300°C.If you want to know more information such as the electrical characteristics about the LT1257CS8,please download the datasheet in www.seekic.com or www.chinaicmart.com .
