LT1225 Very High Speed Operational Amplifier UFEATUSREDESCRIPTIO ■ Gain of 5 Stable The LT1225 is a very high speed operational amplifier with ■ 150MHz Gain Bandwidth excellent DC performance. The LT1225 features reduced ■ 400V/µs Slew Rate input offset voltage and higher DC gain than devices with ■ 20V/mV DC Gain, RL = 500Ω comparable bandwidth and slew rate. The circuit is a ■ 1mV Maximum Input Offset Voltage single gain stage with outstanding settling characteristics. ■ ±12V Minimum Output Swing into 500Ω The fast settling time makes the circuit an ideal choice for ■ Wide Supply Range: ± 2.5V to ±15V data acquisition systems. The output is capable of driving ■ 7mA Supply Current a 500Ω load to ±12V with ±15V supplies and a 150Ω load ■ 90ns Settling Time to 0.1%, 10V Step to ± 3V on ± 5V supplies. The circuit is also capable of ■ Drives All Capacitive Loads driving large capacitive loads which makes it useful in buffer or cable driver applications.
