... Input Capacitance The LTC1047 has approximately 12pF of capacitance at each input pin. This will react with large series resistors to form a pole at the input, degrading the LTC1047's phase margin. The problem is especially common with micropower parts like the LTC1047 because high value resistors are often used to minimize power dissipation rule of thumb, bypass feedback resistors larger than 7k with a 20pF capacitor to minimize this effect ...
