The LT

output current and excellent large-signal characteristics.

The combination of high slew rate, 1.1A output drive and

±15V operation enables the device to deliver significant

power at frequencies in the 1MHz to 2MHz range. Short-

circuit protection and thermal shutdown ensure the

device’s ruggedness. The LT1210 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 and low

supply current mode, reducing dissipation when the

device is not in use. For lower bandwidth applications,

the supply current can be reduced with a single external

resistor.

The LT1210 is available in the TO-220 and DD packages

for operation with supplies up to

±15V. For ±5V applica-

tions the device is also available in a low thermal resis-

tance SO-16 package.
