FEATURES  
DESCRIPTIO  
TheLT®1795isadualcurrentfeedbackamplifierwithhigh  
output current and excellent large signal characteristics.  
The combination of high slew rate, 500mA output drive  
and up to ±15V operation enables the device to deliver  
significant power at frequencies in the 1MHz to 2MHz  
range. Short-circuit protection and thermal shutdown  
insure the device’s ruggedness. The LT1795 is stable with  
large capacitive loads and can easily supply the large  
currents required by the capacitive loading. A shutdown  
feature switches the device into a high impedance, low  
current mode, reducing power dissipation when the de-  
vice is not in use. For lower bandwidth applications, the  
supply current can be reduced with a single external  
resistor.  
500mA Output Drive Current  
50MHz Bandwidth, AV = 2, RL = 25  
900V/µs Slew Rate, AV = 2, RL = 25Ω  
Low Distortion: –75dBc at 1MHz  
High Input Impedance, 10MΩ  
Wide Supply Range, ±5V to ±15V  
Full Rate, Downstream ADSL Supported  
Power Enhanced Small Footprint Packages
