LTC1047 - Linear Technology

LTC1047 Dual Micropower Chopper Stabilized Operational Amplifier

of these types of problems (and some advice on avoiding them), see the LTC1051/LTC1053 data sheet. 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.
