... Note 3: The power tests done on 15V supplies are done on only one amplifier at a time to prevent excessive junction temperatures when testing at maximum operating temperature. Note 4: The supply current of the LT1229/LT1230 has a negative temperature coefficient. For more information see the application information section. ...

... A PPLICATI S I FOR ATIO The LT1229/LT1230 are very fast dual and quad current feedback amplifiers. Because they are current feedback amplifiers, they maintain their wide bandwidth over a wide range of voltage gains. These amplifiers are designed to drive low impedance loads such as cables with excellent linearity at high frequencies ...

... The worst case amplifier power dissipation is the total of the quiescent current times the total power supply voltage plus the power in the IC due to the load. The quiescent supply current of the LT1229/LT1230 has a strong nega- tive temperature coefficient. The supply current of each W U amplifier at 150 C is less than 7mA and typically is only 4 ...

... This is because the input stage and the output stage both have slew rate limitations. The input stage of the LT1229/LT1230 amplifiers slew at about 100V/ s before they become nonlinear. Faster input sig- nals will turn on the normally reverse-biased emitters on the input transistors and enhance the slew rate signifi- cantly ...

... A. The crosstalk from amplifier A’s output (Pin 1) to amplifier B is about 10dB better. The crosstalk between all of the LT1230 amplifiers is as shown. The LT1230 amplifiers that are separated by the supplies are a few dB better. When cascading amplifiers the crosstalk will limit the ...
