Description

The LT1223 is a 100MHz current feedback amplifier with very good DC characteristics. The LT1223's high slew rate, 1000V/µs, wide supply range, ±15V, and large output drive, ±50mA, make it ideal for driving analog signals over double-terminated cables. The current feedback amplifier has high gain bandwidth at high gains, unlike conventional op amps.

The LT1223 comes in the industry standard pinout and can upgrade the performance of many older products.

The LT1223 is manufactured on Linear Technology's proprietary complementary bipolar process.
