Using industry standard pinouts, the dual is available in the 8-pin mini DIP 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 30m A 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 plementary bipolar process. For a single amplifier like these see the LT1227 and for better DC accuracy see the LT1223. , LTC and LT are registered trademarks of Linear Technology Corporation.
