FEATURES
Dual and Quad 100MHz
Current Feedback Amplifiers
The LT
1229/LT1230 dual and quad 100MHz current
feedback amplifiers are designed for maximum perfor-
mance in small packages. Using industry standard pinouts,
the dual is available in the 8-pin miniDIP and the 8-pin SO
package while the quad is in the 14-pin DIP and 14-pin SO.
The amplifiers are designed to operate on almost any
available supply voltage from 4V (
±2V) to 30V (±15V).
These current feedback amplifiers have very high input
impedance and make excellent buffer amplifiers. They
maintain their wide bandwidth for almost all closed-loop
voltage gains. The amplifiers drive over 30mA of output
current and are optimized to drive low impedance loads,
such as cables, with excellent linearity at high frequencies.
The LT1229/LT1230 are manufactured on Linear
Technology’s proprietary complementary bipolar process.
For a single amplifier like these see the LT1227 and for
better DC accuracy see the LT1223.
