LT1223 100MHz Current Feedback Amplifier
U FEATURES DESCRIPTIO
■ 100MHz Bandwidth at AV = 1 The LT®1223 is a 100MHz current feedback amplifier with ■ 1000V/µs Slew Rate very good DC characteristics. The LT1223’s high slew ■ Wide Supply Range: ±5V to ±15V rate, 1000V/µs, wide supply range, ±15V, and large output ■ 1mV Input Offset Voltage drive, ±50mA, make it ideal for driving analog signals over ■ 1µA Input Bias Current double-terminated cables. The current feedback amplifier ■ 5MΩ Input Resistance has high gain bandwidth at high gains, unlike conventional ■ 75ns Settling Time to 0.1% op amps. ■ 50mA Output Current The LT1223 comes in the industry standard pinout and ■ 6mA Quiescent Current can upgrade the performance of many older products. ■ Available in 8-Lead Plastic DIP and SO Packages
