TYPICAL APPLICATION

DESCRIPTION

High Temperature 1.0A,

35MHz Current Feedback Amplifier

The LT®1210X is a current feedback amplifier with high

output current and excellent large-signal characteristics.

The combination of high slew rate, 1.0A output drive and

±15V operation enables the device to deliver significant

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

circuit protection ensures the device’s ruggedness. The

LT1210X is stable with large capacitive loads, and can

easily supply the large currents required by the capaci-

tive 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 LT1210X is a member of a growing series of high

temperature qualified products offered by Analog

Devices. For a complete selection of high temperature

products, please consult our website www.linear.com

The LT1210X is available in the thermally enhanced

TSSOP16-E package for operation with supplies from

±5V up to ±15V. The LT1210X is also available as dice.
