Notes: 1. To improve stability, take notes of the below precautions.

(1) Use capacitor that is temperature independent.

(2) Use capacitor that is bias voltage independent.

(3) No secondary resonance (non-inductive) capacitor.

And, pay attention to the following points so that there can be an efficient bypass of high frequency noise.

(1) To eliminate PCB pattern inductance mount the capacitor as close as possible to the VCC and GND of

IC.

2. For using of the lower limit of recommended value, take notes of the below precautions.

(1) Use capacitor that is temperature independent.

(2) Use capacitor that is bias voltage independent.

(3) No secondary resonance (non-inductive) capacitor.
