Functional Description

1. R

i

Inverting input resistance which sets the closed-loop gain in conjuction with R

forms a high pass filter with C

2. C

i

Input coupling capacitor which blocks the DC voltage at the amplifier’s input terminals. Also creates a

highpass filter with R

Components, for and explanation of how to determine the value of C

3. R

f

Feedback resistance which sets closed-loop gain in conjuction with R

4. C

S

Supply bypass capacitor which provides power supply filtering. Refer to the Application Information

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

5. C

B

Bypass pin capacitor which provides half-supply filtering. Refer to the section, Proper Selection of

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

6. C

O

Output coupling capacitor which blocks the DC voltage at the amplifier’s output. Forms a high pass

filter with R

7. R

B

Resistor which forms a voltage divider that provides a half-supply DC voltage to the non-inverting

input of the amplifier.
