Components, for an explanation of determining the value of C

3. R

f

The feedback resistance, along with R

4. C

S

This is the supply bypass capacitor. It provides power supply filtering. Refer to the Application

Information section for proper placement and selection of the supply bypass capacitor.

5. C

B

This is the BYPASS pin capacitor. It provides half-supply filtering. Refer to the section, Selecting

Proper External Components, for information concerning proper placement and selection of C

6. C

O

This is the output coupling capacitor. It blocks the DC voltage at the amplifier’s output and forms a high

pass filter with R

πR
