LT1210
1.1A, 35MHz Current
Feedback Amplifier
DESCRIPTIO
The LT®1210 is a current feedback amplifier with high
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.
