... V 14682 AI01 Gain of 2 Stable The LT1468 decompensated version of the LT1468. The precision DC performance is identical, but the internal compensation capacitors have been reduced to a point where the op amp needs a gain greater in order to be stable. In general, for applications where the gain around the op amp is ≥ ...

... APPLICATIONS INFORMATION Input Considerations Each input of the LT1468-2 is protected with a 100Ω series resistor and back-to-back diodes across the bases of the input devices. If the inputs can be pulled apart, the input current should be limited to less than 10mA with an external series resistor. Each input also has two ESD clamp diodes— ...
