LT1210X DICE/DWF
High Temperature 200°C,
1.0A, 35MHz Current Feedback Amplifier
DESCRIPTION
FEATURES
The LT®1210X is a current feedback amplifier with high
ꢀutput current and excellent large-signal characteristics.
The cꢀmbinatiꢀn ꢀf high slew rate, 1.0A ꢀutput drive and
±1±5 ꢀperatiꢀn enables the device tꢀ deliver significant
pꢀwer at frequencies in the 1MHz tꢀ 2MHz range. Shꢀrt-
circuit prꢀtectiꢀn ensures the device’s ruggedness. The
LT1210X is stable with large capacitive lꢀads, and can
easilysupplythelargecurrentsrequiredbythecapacitive
lꢀading. A shutdꢀwn feature switches the device intꢀ a
high impedance and lꢀw supply current mꢀde, reduc-
ing dissipatiꢀn when the device is nꢀt in use. Fꢀr lꢀwer
