LT1224 Very High Speed Operational Amplifier FEATURES s s s s s s s s s s DESCRIPTIO Unity-Gain Stable 45MHz Gain-Bandwidth 400V/µs Slew Rate 7V/mV DC Gain: RL = 500Ω Maximum Input Offset Voltage: 2mV ±12V Minimum Output Swing into 500Ω Wide Supply Range: ±2.5V to ±15V 7mA Supply Current 90ns Settling Time to 0.1%, 10V Step Drives All Capacitive Loads The LT1224 is a very high speed operational amplifier with excellent DC performance. The LT1224 features reduced input offset voltage and higher DC gain than devices with comparable bandwidth and slew rate. The circuit is a single gain stage with outstanding settling characteristics. The fast settling time makes the circuit an ideal choice for data acquisition systems. The output is capable of driving a 500Ω load to ±12V with ±15V supplies and a 150Ω load to ±3V on ±5V supplies. The circuit is also capable of driving large capacitive loads which makes it useful in buffer or cable driver applications. The LT1224 is a member of a family of fast, high performance amplifiers that employ Linear Technology Corporation’s advanced bipolar complementary processing.
