LT1360 50MHz, 800V/µs Op Amp UFEATURESDESCRIPTIO ■ 50MHz Gain Bandwidth The LT1360 is a high speed, very high slew rate opera- ■ 800V/ µ s Slew Rate tional amplifier with excellent DC performance. The LT1360 ■ 5mA Maximum Supply Current features reduced supply current, lower input offset volt- ■ 9nV/√Hz Input Noise Voltage age, lower input bias current and higher DC gain than ■ Unity-Gain Stable devices with comparable bandwidth. The circuit topology ■ C-LoadTM Op Amp Drives All Capacitive Loads is a voltage feedback amplifier with the slewing character- ■ 1mV Maximum Input Offset Voltage istics of a current feedback amplifier. The amplifier is a ■ 1µA Maximum Input Bias Current single gain stage with outstanding settling characteristics ■ 250nA Maximum Input Offset Current which makes the circuit an ideal choice for data acquisition ■ ±13V Minimum Output Swing into 500Ω systems. The output drives a 500Ω load to ±13V with ±15V ■ ±3.2V Minimum Output Swing into 150Ω supplies and a 150Ω load to ±3.2V on ±5V supplies. The ■ 4.5V/mV Minimum DC Gain, RL=1k amplifier is also capable of driving any capacitive load ■ 60ns Settling Time to 0.1%, 10V Step which makes it useful in buffer or cable driver applications. ■ 0.2% Differential Gain, AV=2, RL=150Ω The LT1360 is a member of a family of fast, high ■ 0.3° Differential Phase, AV=2, RL=150Ω performance amplifiers using this unique topology and ■ Specified at ±2.5V, ±5V, and ±15V employing Linear Technology Corporation’s advanced bipolar complementary processing.
