RH1814M Quad 3mA, 100MHz, 750V/µs Operational Amplifier U The output drives a 100Ω load to ±3.35V with ±5V supplies. On a single 5V supply, the output swings from 1.1V to 3.7V with a 100Ω load connected to 2.5V. The amplifiers are stable with a 1000pF capacitive load making them useful in buffer and cable driver applications. W The RH1814 is a quad, low power, high speed, very high slew rate operational amplifier with excellent DC performance, reduced supply current, lower input offset voltage, lower input bias current and higher DC gain than other devices with comparable bandwidth. The circuit topology is a voltage feedback amplifier with the slewing characteristics of a current feedback amplifier.
