LT1795

1795fa

The LT

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.
