External Components Description (Figure 1)
Components
Functional Description
1. R
i
The inverting input resistance, along with R
f, set the closed-loop gain. Ri, along with Ci, form a high
pass filter with f
c = 1/(2
πR
iCi).
2. C
i
The input coupling capacitor blocks DC voltage at the amplifier’s input terminals. C
i, along with Ri,
create a highpass filter with f
C = 1/(2
πR
iCi). Refer to the section, Selecting Proper External
Components, for an explanation of determining the value of C
i.
3. R
f
The feedback resistance, along with R
i, set closed-loop gain.
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 half-supply 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
B.
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
L at fO = 1/(2
πR
LCO)
7. R
B
This is the resistor which forms a voltage divider that provides 1/2 V
DD to the non-inverting input of the
amplifier.
