TECHNICAL NOTES
this purpose, be sure to use a capacitor C
Resistance) in the range described as follows:
when the white noise level is under 40µV (Avg.) are marked as the hatched area in the graph.
<Test conditions>
(1) Frequency band: 10Hz to 2MHz
When using these ICs, consider the following points:
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
