LT1795
1795fa
The LT
1795 is a dual current feedback amplifier with high
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.
The LT1795 comes in the very small, thermally enhanced,
20-lead TSSOP package for maximum port density in line
driver applications.
