Page 1
... The LT 1812 is a low power, high speed, very high slew rate operational amplifier with excellent DC performance. The LT1812 features reduced supply current, lower input offset voltage, lower input bias current and higher DC gain than other devices with comparable bandwidth. A power saving shutdown feature reduces supply current ...

... Highest slew rates are therefore seen in the lowest gain configurations. For example output step in a gain of 10 has a 0.5V input step, whereas in unity gain there input step. The LT1812 is tested for slew rate in a gain of – 1. Lower slew rates occur in higher gain configurations. ...

... RC combination adds phase to ensure that the total phase lag does not exceed 180 degrees (zero phase margin) and the amplifier remains stable. In this way, the LT1812 is stable with up to 1000pF capacitive loads in unity gain, and even higher capacitive loads in higher closed-loop gain configurations ...
