Linear Technology LT1252
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.FEATURES
s s s s s s s s DESCRIPTIO Low Cost Current Feedback Amplifier Differential Gain: 0.01%, RL = 150Ω, VS = ± 5V Differential Phase: 0.09°, RL = 150Ω, VS = ± 5V Flat to 30MHz, 0.1dB 100MHz Bandwidth on ± 5V Wide Supply Range: ± 2V(4V) to ± 14V(28V) Low Power: 85mW at ± 5V The linearity of the LT1252 is outstanding; it is unsurpassed 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.
