DESCRIPTIO
The LT^®1223 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.
