The bination 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. Shortcircuit 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 applications the device is also available in a low thermal resistance SO-16 package. , LTC and LT are registered trademarks of Linear Technology Corporation.
