Components

Functional Description

2.

C

i

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

highpass filter with R

πR

for an explanation of how to determine the value of C

3.

R

f

Feedback resistance which sets the closed-loop gain in conjunction with R

4.

C

s

Supply bypass capacitor which provides power supply filtering. Refer to the Power Supply Bypassing

section for information concerning 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 the single-ended load R
