Typical Performance Characteristics
Supply bypass capacitor is 0.1 μF and filter capacitor is
0.1 μF. (Continued)
Note 10:
These curves represent a statistical average such that the noise is insignificant.
Typical Application Circuits
In the application circuits, the 0.1 μF ceramic capacitor between pins 1 and 2
is used for bypassing, and the 0.1 μF ceramic capacitor between pins 3 and 4 is used for filtering. Shutdown (SD) is tied to
V
DD
through a 10 k
resistor.
